Auth: Authorization: Bearer hm_live_<your_api_key>

Learn how to use the HuMetric API for entity metrics, signal processing, and semantic queries.

---

## Four words to know first

- **Entity**: The thing you measure — an agent, a user, a task. Everything in HuMetric hangs off an entity and the ID you give it.
- **Signal**: A piece of evidence about an entity: free text or structured data. You send signals; HuMetric reads them.
- **Metric**: A calibrated 0–1 score HuMetric extracts from signals. Each carries a confidence and fades as it ages.
- **Pack**: Your scoring rules. A pack declares which metrics to extract for an entity type — define it once, reuse it forever.
- **Confidence**: How sure HuMetric is about a value. It is recorded once and never rewritten — but its weight decays as the evidence ages, so a stale score quietly stops counting.
- **Consent**: A pack can mark a metric sensitive. Those values stay hidden until the entity has granted the matching consent scope, and disappear again the moment it is revoked.

## Zero to metrics in four calls

The order matters. A signal is rejected until its entity exists, and metrics stay empty until a pack tells HuMetric what to look for.

1. `POST /v1/packs` — **Define a pack**: Tell HuMetric what to measure for an entity type — e.g. agents get code_quality and helpfulness.
2. `POST /v1/entities` — **Create an entity**: Register the thing you’ll track. Signals are rejected until the entity exists.
3. `POST /v1/signals` — **Send signals**: Feed evidence as it happens. HuMetric extracts metrics and updates them in the background.
4. `GET /v1/entities/{id}/metrics` — **Read or rank**: Pull one entity’s live metrics, or query in plain language across all of them.

## Keys and scopes

All API requests require a valid HuMetric API key. Include the key as a Bearer token in the Authorization header. Create your API key from the dashboard after registration.

```
Authorization: Bearer hm_live_K4f8xY2pL9mN3vR7wQ1sT6uZ0bC5dA...
```

Keys come in two prefixes. hm_live_ keys act on your real data; hm_test_ keys are for wiring things up. The full key is shown once, at creation — HuMetric only stores a hash, so a lost key must be replaced, not recovered.

Keys can carry an expiry (up to 730 days). Rotating is create-then-delete: mint the new key, move your traffic, then revoke the old one. A key cannot delete itself.

### Scopes

- `entities:read`: Read entities, their metrics, explanations, and history.
- `entities:write`: Create and update entities, and override a metric under review.
- `signals:read`: Read signal status, traces, and an entity’s signal list.
- `signals:write`: Submit new signals for processing.
- `query`: Run semantic queries and rankings across entities.
- `packs:read`: List and read metric packs.
- `packs:admin`: Create, update, and generate packs. Implies read.
- `tenant:admin`: Read account usage and manage tenant-level settings. Required by /v1/usage and /v1/usage/calls.

A key can only ever create keys weaker than or equal to itself, so a narrow integration key cannot quietly widen its own reach.

## Connect Claude directly — no code required

The Model Context Protocol (MCP) lets Claude Desktop or Claude Code talk to your HuMetric account directly. Once it’s connected, just ask in plain language — Claude queries entities, reads scores, and can log new signals for you, right from the chat.

```bash
curl -O https://raw.githubusercontent.com/bestekarx/humetric/main/mcp_server.py
pip install mcp httpx python-dotenv
```

### Claude Desktop

Add to claude_desktop_config.json:

```json
{
  "mcpServers": {
    "humetric": {
      "command": "python3",
      "args": ["/path/to/mcp_server.py", "--transport", "stdio"],
      "env": {
        "HUMETRIC_MCP_API_KEY": "hm_live_your_key_here",
        "HUMETRIC_BASE_URL": "https://api.gethumetric.com"
      }
    }
  }
}
```

### Claude Code

Run once in your terminal:

```json
claude mcp add humetric \
+  -e HUMETRIC_MCP_API_KEY=hm_live_your_key_here \
+  -e HUMETRIC_BASE_URL=https://api.gethumetric.com \
+  -- python3 /path/to/mcp_server.py --transport stdio
```

## Rules that hold everywhere

### Writes are asynchronous

POST /v1/signals answers 202 with a signal_id and a trace_url before any work happens. The status it returns is "received" — never "queued". Extraction runs in the background and moves the signal to "completed" or "failed"; a retried signal goes back to "received". Metrics are never up to date in the same call that produced them, so poll the signal or re-read the entity.

### Pagination

Most list endpoints take limit and offset and answer with items, total, limit, offset — but not all of them, so check the shape per endpoint below. Metric history returns points instead of items. GET /v1/packs, GET /v1/consent/{entity_id} and GET /v1/metrics/pending-review return a bare JSON array with no envelope and no paging at all. GET /v1/api-keys returns {api_keys: […]} with no total. Where limit is accepted, asking above the ceiling is clamped silently rather than rejected.

### Timestamps

Every timestamp in and out is ISO 8601. Send UTC; a value without a timezone is read as UTC. occurred_at may not be in the future.

### Re-sending a signal

Idempotency is the Idempotency-Key request header, not a body field. Send the same header value again for the same entity within 24 hours and you get 200 with the original signal and its metrics instead of a second queue entry — that is what makes a webhook retry safe. Two things to be careful about. external_id on its own does not give you this: the replay check only runs when the header is present, and because both write to the same unique column, re-sending an external_id you have already used for that entity fails with 500 rather than returning the original. The same is true of a header value replayed after the 24-hour window has passed. So treat an idempotency value as single-use per entity per day: send it as the header, keep it unique, and do not reuse yesterday’s.

### confidence vs effective_confidence

confidence is what was recorded at the time — the honest line to plot. effective_confidence applies exponential temporal decay at read time, with a half-life of 365 days: what that evidence is still worth today. They are not interchangeable; rank on the effective one, chart the raw one. Note that POST /v1/signals results and GET /v1/metrics/pending-review carry the raw confidence only.

### Field naming

Responses are always snake_case. Requests are mostly snake_case too: camelCase is accepted only on the specific fields listed below, because each alias was added by hand rather than by a naming rule. Anything not on that list is rejected with 422 — entityId, entityType and externalId on POST /v1/signals are the ones people hit first. Send snake_case everywhere and none of this matters.

### Where camelCase is accepted

- `POST /v1/entities`: Id, entityType, freeText
- `POST /v1/signals`: occurredAt
- `POST /v1/query`: rankBy, freeTextQuery, includeReasoning
- `POST /v1/packs`: packKey
- `POST /v1/packs/wizard`: entityTypeHint
- `POST /v1/consent`: expiresAt

### Per-endpoint ceilings

- `GET /v1/entities` — limit: default 20, ceiling 100
- `GET /v1/entities/{id}/signals` — limit: default 50, ceiling 100
- `GET /v1/entities/{id}/metrics/{key}/history` — limit: default 200, ceiling 500
- `GET /v1/entities/{id}/metrics/{key}/explain` — contributions: default 10, ceiling 100
- `GET /v1/audit-logs` — limit: default 100, ceiling 500
- `GET /v1/usage/calls` — limit: default 100, ceiling 500
- `POST /v1/query` — top_k: default 10, ceiling 100
- `GET /v1/entities/{id}/metrics` — include_history: default —, ceiling 30
- `GET /v1/metrics/pending-review` — —: default 50, ceiling 50

## Full API reference

30 endpoints, ordered the way you meet them. Each one lists the API-key scope it requires.

### Packs

Define what to measure.

#### POST /v1/packs

**Create Pack** — https://gethumetric.com/en/docs#post-v1-packs

Create a metric pack definition in YAML format. A pack defines which metrics to extract for an entity_type.

Required scope: `packs:admin`
Success status: 201

Parameters:
  - yaml_text [string] (required): Pack definition (YAML)
  - pack_key [string] (optional): Pack key (auto: entity_type)

Request:
```bash
curl -X POST https://api.gethumetric.com/v1/packs \
  -H "Authorization: Bearer hm_live_xxxx..." \
  -H "Content-Type: application/json" \
  -d '{"yaml_text": "entity_type: agent\nlabel: Agent Quality\nmetrics:\n  - key: code_quality\n    label: Code Quality\n    type: float\n    prompt: Rate code quality from 0 to 1"}'
```

Response:
```json
{
  "pack_key": "agent",
  "version": 1,
  "label": "AI Agent Quality",
  "entity_type": "agent",
  "is_active": true,
  "created_at": "2026-08-24T19:39:17.997229Z",
  "updated_at": null
}
```

The stored pack: pack_key, version, label, entity_type, is_active, and timestamps.

Note: One active pack per entity_type. Creating a second pack for a type that already has one returns 409 entity_type_already_active — update the existing pack instead. A duplicate pack_key returns 409 pack_already_exists.

**List Packs** — https://gethumetric.com/en/docs#get-v1-packs

List all your metric pack definitions.

Required scope: `packs:read`

Parameters:
  - is_active [boolean (query)] (optional): Fetch only active packs

Request:
```bash
curl -X GET "https://api.gethumetric.com/v1/packs?is_active=true" \
  -H "Authorization: Bearer hm_live_xxxx..."
```

Response:
```json
[
  {
    "pack_key": "agent",
    "version": 1,
    "label": "AI Agent Quality",
    "entity_type": "agent",
    "is_active": true,
    "created_at": "2026-08-24T19:39:17.997229Z",
    "updated_at": null
  }
]
```

An array of pack summaries. Pass is_active=true to skip retired versions.

---

#### GET /v1/packs/{pack_key}

**Get a pack** — https://gethumetric.com/en/docs#get-v1-packs-pack-key

Fetch one pack by key, including its full parsed definition — the metrics, required fields, bands, and KVKK flags it declares.

Required scope: `packs:read`

Parameters:
  - pack_key [string (path)] (required): The pack’s key, as returned when it was created.

Request:
```bash
curl -X GET "https://api.gethumetric.com/v1/packs/agent-quality" \
  -H "Authorization: Bearer hm_live_xxxx..."
```

Response:
```json
{
  "pack_key": "agent",
  "version": 1,
  "label": "AI Agent Quality",
  "entity_type": "agent",
  "is_active": true,
  "created_at": "2026-08-24T19:39:17.997229Z",

        "label": "Task Success",
        "type": "float",
        "prompt": "Did the agent resolve the request completely and correctly?",
        "direction": "higher_is_better",
        "default_confidence": 0.6,
        "sensitive": false,
        "visible_to": [],
        "unit": "",
        "bands": [],
        "allow_unknown": false
      }
    ],
    "kvkk": { "sensitive_metrics": [] },
    "display": { "title_field": "", "subtitle_field": "", "primary_metrics": [], "groups": [] }
  }
}
```

The pack summary plus its complete definition object.

---

#### PUT /v1/packs/{pack_key}

**Update a pack** — https://gethumetric.com/en/docs#put-v1-packs-pack-key

Replace a pack’s definition with new YAML. Use this to add a metric, retune a prompt, or adjust bands without breaking the entities already scored by it.

Required scope: `packs:admin`

Parameters:
  - pack_key [string (path)] (required): The pack’s key, as returned when it was created.
  - yaml_text [string] (required): Pack definition (YAML)

Request:
```bash
curl -X PUT "https://api.gethumetric.com/v1/packs/agent-quality" \
  -H "Authorization: Bearer hm_live_xxxx..." \
  -H "Content-Type: application/json" \
  -d '{"yaml_text": "entity_type: agent\nlabel: Agent Quality\nversion: 2\nmetrics:\n  - key: code_quality\n    label: Code Quality\n    type: float\n    prompt: Rate code quality from -1 to 1"}'
```

Response:
```json
{
  "pack_key": "agent",
  "version": 2,
  "label": "AI Agent Quality",
  "entity_type": "agent",
  "is_active": true,
  "created_at": "2026-08-24T19:39:17.997229Z",
  "updated_at": "2026-08-24T19:39:18.057553Z"
}
```

The updated pack, with its version incremented.

Note: Editing a pack does not rescore existing metrics — it changes what future signals extract. Old values stay until new evidence arrives. Changing entity_type on a live pack is rejected.

---

#### POST /v1/packs/wizard

**Generate a pack with AI** — https://gethumetric.com/en/docs#post-v1-packs-wizard

Describe what you want to measure in plain language and get back a valid pack YAML. The wizard picks the metrics, writes their extraction prompts, and validates the result before returning it.

Required scope: `packs:admin`

Parameters:
  - text [string] (required): What you want to measure, in plain language. 10–100,000 characters — more context yields better metrics.
  - entity_type_hint [string] (optional): The entity type to write into the generated pack. Inferred from your description when omitted.

Request:
```bash
curl -X POST https://api.gethumetric.com/v1/packs/wizard \
  -H "Authorization: Bearer hm_live_xxxx..." \
  -H "Content-Type: application/json" \
  -d '{"text": "I run a marketplace and want to score sellers on shipping speed, product accuracy, and how they handle complaints", "entity_type_hint": "seller"}'
```

Response:
```json
{
  "yaml_text": "entity_type: dealer\nlabel: Dealer\nversion: 1\nmetrics:\n  - key: churn_risk\n    ...",
  "entity_type": "dealer",
  "model": "<configured wizard model>"
}
```

pack_yaml ready to send to POST /v1/packs, plus validation_errors and a confidence score for the suggestion.

Note: The wizard only drafts — nothing is saved. Review the YAML, then create it yourself. A non-empty validation_errors means the draft needs an edit before it will be accepted.

### Entities

Register the things you track, and read their metrics.

#### POST /v1/entities

**Create / Update Entity** — https://gethumetric.com/en/docs#post-v1-entities

Create a new entity or update an existing one. Entities are the units that metrics are attached to (user, agent, task, etc.).

Required scope: `entities:write`
Success status: 201

Parameters:
  - id [string] (required): Client-determined unique ID
  - entity_type [string] (required): Entity type (e.g. agent, user, task)
  - fields [object] (optional): Custom fields (key-value)
  - free_text [string] (optional): Free text about the entity

Request:
```bash
curl -X POST https://api.gethumetric.com/v1/entities \
  -H "Authorization: Bearer hm_live_xxxx..." \
  -H "Content-Type: application/json" \
  -d '{"id": "agent-42", "entity_type": "agent", "fields": {"name": "Claude", "version": "4.5"}, "free_text": "Code help assistant"}'
```

Response:
```json
{
  "id": "agent-42",
  "entity_type": "agent",
  "fields": { "name": "Support Copilot" },
  "free_text": "Handles tier-1 billing questions.",
  "metrics": [],
  "status": "active",
  "created_at": "2026-08-24T19:39:18.082991Z",
  "updated_at": null
}
```

The created entity with an empty metrics array — scores appear only after signals are processed.

Note: The id is yours to choose and must be unique within your tenant; reuse the ID your own system already has. Sending an existing ID updates that entity rather than creating a second one. There must be an active pack for the entity_type first.

---

#### GET /v1/entities

**List entities** — https://gethumetric.com/en/docs#get-v1-entities

Page through the entities you have registered, newest first, optionally narrowed to one type.

Required scope: `entities:read`

Parameters:
  - entity_type [string (query)] (optional): Filter by entity type
  - limit [number (query)] (optional): Rows per page. Default 20, maximum 100.
  - offset [number (query)] (optional): How many rows to skip. Combine with limit to page.

Request:
```bash
curl -X GET "https://api.gethumetric.com/v1/entities?entity_type=agent&limit=20&offset=0" \
  -H "Authorization: Bearer hm_live_xxxx..."
```

Response:
```json
{
  "items": [
    {
      "id": "agent-42",
      "entity_type": "agent",
      "fields": { "name": "Support Copilot" },
      "free_text": "Handles tier-1 billing questions.",
      "metrics": [],
      "status": "active",
      "created_at": "2026-08-24T19:39:18.082991Z",
      "updated_at": null
    }
  ],
  "total": 1,
  "limit": 20,
  "offset": 0
}
```

items with total, limit, offset. Each item carries its current metrics.

---

#### GET /v1/entities/{entity_id}

**Get Entity** — https://gethumetric.com/en/docs#get-v1-entities-entity-id

Retrieve entity details and current metrics.

Required scope: `entities:read`

Parameters:

  "updated_at": "2026-08-24T19:41:02.118004Z"
}
```

The entity with its fields, free_text, status, and current metrics.

---

#### GET /v1/entities/{entity_id}/metrics

**Entity Metrics** — https://gethumetric.com/en/docs#get-v1-entities-entity-id-metrics

```

Response:
```json
{
  "entity_id": "agent-42",
  "metrics": [
    {
      "metric_key": "task_success",

    }
  ],
  "metric_count": 1,
  "history": {}
}
```

Every current metric with value, confidence, effective_confidence, source_count, and last_updated.

Note: Sensitive metrics are omitted unless the entity has granted the consent scope the pack requires — the response is simply shorter, it does not error.

    }
  ],
  "total": 1,
  "limit": 200,

}
```

points with recorded_at, value, prev_value, delta, confidence, effective_confidence, and the signal that caused each write.

Note: The timeline follows occurred_at, not arrival time — backfilled signals land in the right place in history. Plot confidence for the honest record and effective_confidence for what still counts today.

#### GET /v1/entities/{entity_id}/signals

**List an entity’s signals** — https://gethumetric.com/en/docs#get-v1-entities-entity-id-signals

Everything you have sent about one entity, with a text preview and the metrics each signal produced — the audit trail behind its scores.

Required scope: `signals:read`

Parameters:
  - entity_id [string (path)] (required): Target entity ID
  - status [string (query)] (optional): Filter by processing status: received, processing, completed, or failed. Any other value is accepted but matches nothing.
  - limit [number (query)] (optional): Rows per page. Default 50, maximum 100.
  - offset [number (query)] (optional): How many rows to skip. Combine with limit to page.

Request:
```bash
curl -X GET "https://api.gethumetric.com/v1/entities/agent-42/signals?status=completed&limit=50" \
  -H "Authorization: Bearer hm_live_xxxx..."
```

Response:
```json
{
  "items": [
    {
      "id": "e5f19c59-ac91-472a-88bf-54b75df0ddf3",
      "external_id": null,
      "status": "completed",
      "entity_id": "agent-42",
      "pack_key": "agent",
      "source": null,
      "text_preview": "The customer asked to split an invoice across two cost centres…",
      "metric_keys": ["task_success", "tone"],
      "occurred_at": "2026-08-20T09:15:00Z",
      "created_at": "2026-08-24T19:39:18.157567Z",
      "processed_at": "2026-08-24T19:39:18.810829Z"
    }
  ],
  "total": 1,
  "limit": 50,
  "offset": 0
}
```

items with total, limit, offset. Each row carries status, source, text_preview, and metric_keys, but not the full text or trace.

---

### Signals

Feed in evidence and follow how it’s processed.

#### POST /v1/signals

**Send Signal** — https://gethumetric.com/en/docs#post-v1-signals

Submit raw text or structured data for an entity. HuMetric processes this signal, extracts metrics, and updates them.

Required scope: `signals:write`
Success status: 202

Parameters:
  - entity_id [string] (required): Target entity ID
  - entity_type [string] (required): Entity type (e.g. agent, user, task)
  - text [string] (optional): Free text (e.g. user feedback)
  - structured [object] (optional): Structured data (key-value)
  - external_id [string] (optional): Your own id for this signal, stored for reconciliation. It does not make the request idempotent — use the Idempotency-Key header for that. It must still be unique per entity: re-sending one you have already used fails with 500.
  - occurred_at [datetime] (optional): When the source text was actually produced. Omit for live signals; set it when backfilling so history keeps the right order. Cannot be in the future.
  - Idempotency-Key [string (header)] (optional): Request header, not a body field. Re-sending the same value for the same entity within 24 hours returns the original signal with 200 instead of queueing a second one.

Request:
```bash
curl -X POST https://api.gethumetric.com/v1/signals \
  -H "Authorization: Bearer hm_live_xxxx..." \
  -H "Content-Type: application/json" \
  -d '{"entity_id": "agent-42", "entity_type": "agent", "text": "Solved the user request quickly and accurately"}'
```

Response:
```json
{
  "signal_id": "e5f19c59-ac91-472a-88bf-54b75df0ddf3",
  "status": "received",
  "trace_url": "/v1/signals/e5f19c59-ac91-472a-88bf-54b75df0ddf3/trace"
}
```

signal_id, a status of "received", and a trace_url. Poll GET /v1/signals/{signal_id} or read the entity’s metrics once processing finishes.

Note: Returns 202, not 200 — the metrics do not exist yet. Send text, structured, or both. The entity must already exist and must not be archived. Set occurred_at when backfilling so history stays in the right order.

#### GET /v1/signals/{signal_id}

**Signal Status** — https://gethumetric.com/en/docs#get-v1-signals-signal-id

Query the processing status of a submitted signal.

Required scope: `signals:read`

Parameters:
  - signal_id [string (path)] (required): Signal ID

Request:
```bash
curl -X GET "https://api.gethumetric.com/v1/signals/550e8400-e29b-41d4-a716-446655440000" \
  -H "Authorization: Bearer hm_live_xxxx..."
```

Response:
```json
{
  "signal_id": "e5f19c59-ac91-472a-88bf-54b75df0ddf3",
  "status": "completed",
  "entity_id": "agent-42",
  "metrics": [
    { "metric_key": "task_success", "value": 0.72, "confidence": 0.88 }
  ],
  "error": null,
  "created_at": "2026-08-24T19:39:18.157567Z",
  "processed_at": "2026-08-24T19:39:18.810829Z"
}
```

status — one of received, processing, completed or failed — plus timestamps, the metrics once it completes, and an error message if it failed.

---

#### GET /v1/signals/{signal_id}/trace

**Signal Trace** — https://gethumetric.com/en/docs#get-v1-signals-signal-id-trace

View the full processing trace of a signal (extraction, curation, metrics).

Required scope: `signals:read`

Parameters:
  - signal_id [string (path)] (required): Signal ID

Request:
```bash
curl -X GET "https://api.gethumetric.com/v1/signals/550e8400-e29b-41d4-a716-446655440000/trace" \
  -H "Authorization: Bearer hm_live_xxxx..."
```

Response:
```json
{
  "signal_id": "e5f19c59-ac91-472a-88bf-54b75df0ddf3",
  "entity_id": "agent-42",
  "status": "completed",
  "text": "The customer asked to split an invoice across two cost centres…",
  "extracted": [
    {
      "metric_key": "task_success",
      "value": 0.9,
      "confidence": 0.9,
      "reasoning": "Split the invoice in one pass and confirmed the new totals.",
      "source_span": "did it in one pass and confirmed the new totals back to them"
    }
  ],
  "entity_metrics": [
    { "metric_key": "task_success", "value": 0.72, "confidence": 0.88 }
  ],
  "created_at": "2026-08-24T19:39:18.157567Z",
  "processed_at": "2026-08-24T19:39:18.810829Z"
}
```

The full processing trace: the original text, the extractor output, the curator’s merge decision, and the models used at each step.

Note: The trace is the receipt for a score. Use it when a number looks wrong and you need to see which sentence produced it.

---

### Query

Search and rank across entities in plain language.

#### POST /v1/query

**Semantic Query** — https://gethumetric.com/en/docs#post-v1-query

Perform semantic search across entities using free text. Returns the best matches via vector embedding + LLM ranking.

Required scope: `query`

Parameters:
  - free_text_query [string] (optional): Natural language query
  - entity_type [string] (optional): Filter by entity type
  - rank_by [string] (optional): Ranking metric (e.g. code_quality)
  - filters [object] (optional): Exact-match constraints on entity fields, applied before ranking.
  - top_k [number] (optional): Number of results (default 10, max 100)
  - include_reasoning [boolean] (optional): Include LLM ranking explanations

Request:
```bash
curl -X POST https://api.gethumetric.com/v1/query \
  -H "Authorization: Bearer hm_live_xxxx..." \
  -H "Content-Type: application/json" \
  -d '{"free_text_query": "agents with highest code quality", "entity_type": "agent", "top_k": 5}'
```

Response:
```json
{
  "results": [
    {
      "entity_id": "agent-42",
      "entity_type": "agent",
      "score": 0.72,
      "metrics": [
        { "metric_key": "task_success", "value": 0.72, "confidence": 0.88 }
      ],
      "reasoning": "Highest sustained task success with the most evidence behind it."
    }
  ],
  "top_k": 5,
  "model": "<configured curator model>"
}
```

Ranked results with entity_id, score, and metrics — plus a reasoning line per result when include_reasoning is set.

Note: free_text_query searches semantically; rank_by sorts by one metric key. Combine them to search in language and order by a number. filters narrows on entity fields before ranking, which is cheaper than filtering afterwards.

---

### Consent

Grant, inspect, and revoke access to sensitive metrics.

#### POST /v1/consent

**Grant consent** — https://gethumetric.com/en/docs#post-v1-consent

Record that an entity has consented to a named scope. Metrics the pack marked sensitive under that scope become readable from this point on.

Required scope: `entities:write`
Success status: 201

Parameters:
  - entity_id [string] (required): Target entity ID
  - scope [string] (required): The consent scope being granted. Must match the pack’s requires_consent_scope exactly.
  - status [string] (optional): granted, revoked, or expired. Defaults to granted.
  - expires_at [datetime] (optional): When the consent lapses on its own. Omit for open-ended consent.

Request:
```bash
curl -X POST https://api.gethumetric.com/v1/consent \
  -H "Authorization: Bearer hm_live_xxxx..." \
  -H "Content-Type: application/json" \
  -d '{"entity_id": "account-17", "scope": "billing:read", "status": "granted", "expires_at": "2027-01-01T00:00:00Z"}'
```

Response:
```json
{
  "id": 21,
  "entity_id": "agent-42",
  "scope": "health_data",
  "status": "granted",
  "granted_at": "2026-08-24T19:39:30.783606Z",
  "revoked_at": null,
  "expires_at": null
}
```

The stored consent record with granted_at and, if set, expires_at.

Note: The scope string must match the pack’s requires_consent_scope exactly. Consent is per entity, not per tenant — granting it for one entity reveals nothing about another.

Deeper reading: https://gethumetric.com/en/blog/ready-made-metric-pack-for-contact-centres

---

#### GET /v1/consent/{entity_id}

**List consents** — https://gethumetric.com/en/docs#get-v1-consent-entity-id

Every consent record held for one entity — what was granted, when, and whether it is still live.

Required scope: `entities:read`

Parameters:
  - entity_id [string (path)] (required): Target entity ID

Request:
```bash
curl -X GET "https://api.gethumetric.com/v1/consent/account-17" \
  -H "Authorization: Bearer hm_live_xxxx..."
```

Response:
```json
[
  {
    "id": 21,
    "entity_id": "agent-42",
    "scope": "health_data",
    "status": "granted",
    "granted_at": "2026-08-24T19:39:30.783606Z",
    "revoked_at": null,
    "expires_at": null
  }
]
```

An array of consent records with scope, status (granted, revoked, or expired), and timestamps.

---

#### DELETE /v1/consent/{entity_id}

**Revoke consent** — https://gethumetric.com/en/docs#delete-v1-consent-entity-id

Withdraw consent for one scope, or for every scope at once by omitting the scope parameter.

Required scope: `entities:write`

Parameters:
  - entity_id [string (path)] (required): Target entity ID
  - scope [string (query)] (optional): Which scope to revoke. Omit to revoke every scope for this entity.

Request:
```bash
curl -X DELETE "https://api.gethumetric.com/v1/consent/account-17?scope=billing:read" \
  -H "Authorization: Bearer hm_live_xxxx..."
```

Response:
```json
{
  "revoked": true,
  "entity_id": "agent-42",
  "scope": "health_data"
}
```

A confirmation naming the entity and the scope that was revoked (or "all").

Note: Revocation takes effect immediately on every read path — the metric vanishes from GET /metrics, from query results, and from explanations on the next call.

---

### API keys

Mint scoped keys and retire them.

#### POST /v1/api-keys

**Create an API key** — https://gethumetric.com/en/docs#post-v1-api-keys

Mint a scoped key for one integration. Give each consumer its own key with the narrowest scope set that works.

Success status: 201

Parameters:
  - prefix [string] (optional): hm_live for real data or hm_test for integration work. Defaults to hm_test.
  - scopes [string[]] (optional): Scopes the key may use. Cannot exceed the scopes of the key making the request.
  - label [string] (optional): A human name for the key, so you can tell them apart later.
  - expires_in_days [number] (optional): Lifetime in days, 1–730. Simpler than computing an absolute date.
  - expires_at [datetime] (optional): An absolute expiry timestamp. Use this or expires_in_days, not both.

Request:
```bash
curl -X POST https://api.gethumetric.com/v1/api-keys \
  -H "Authorization: Bearer hm_live_xxxx..." \
  -H "Content-Type: application/json" \
  -d '{"prefix": "hm_live", "label": "CRM sync", "scopes": ["signals:write", "entities:read"], "expires_in_days": 365}'
```

Response:
```json
{
  "id": 11,
  "prefix": "hm_live",
  "full_key": "hm_live_<shown once, never again>",
  "scopes": ["signals:write", "entities:read", "query"],
  "label": "ingest-worker",
  "is_revoked": false,
  "created_at": "2026-08-24T19:44:10.201883Z",
  "expires_at": "2027-08-24T19:44:10.201883Z"
}
```

The key record plus full_key — the only time the complete secret is ever returned.

Note: Store full_key immediately; HuMetric keeps only a hash and cannot show it again. You cannot request scopes your own key does not hold. expires_in_days accepts 1–730.

---

#### GET /v1/api-keys

**List API keys** — https://gethumetric.com/en/docs#get-v1-api-keys

Every key on your account with its scopes, label, expiry, and when it was last used — the fastest way to spot a key nothing is calling anymore.

Request:
```bash
curl -X GET https://api.gethumetric.com/v1/api-keys \
  -H "Authorization: Bearer hm_live_xxxx..."
```

Response:
```json
{
  "api_keys": [
    {
      "id": 10,
      "prefix": "hm_live",
      "scopes": ["signals:write", "entities:read", "query"],
      "label": "ingest-worker",
      "is_revoked": false,
      "last_used_at": "2026-08-24T19:39:30.852343Z",
      "created_at": "2026-08-24T19:38:52.748418Z",
      "expires_at": null
    }
  ]
}
```

An array of key records. Secrets are never included, only the prefix.

---

#### DELETE /v1/api-keys/{key_id}

**Revoke an API key** — https://gethumetric.com/en/docs#delete-v1-api-keys-key-id

Retire a key. It stops authenticating immediately and every later request with it returns 401.

Parameters:
  - key_id [number (path)] (required): The numeric id of the key, as returned by GET /v1/api-keys.

Request:
```bash
curl -X DELETE "https://api.gethumetric.com/v1/api-keys/42" \
  -H "Authorization: Bearer hm_live_xxxx..."
```

Response:
```json
{
  "status": "deleted",
  "id": 11
}
```

A confirmation with the deleted key id.

Note: A key cannot revoke itself — that would lock you out mid-rotation. Create the replacement first, switch your traffic to it, then use the new key to revoke the old one.

---

### Review

Catch low-confidence scores and correct them by hand.

#### GET /v1/metrics/pending-review

**List metrics needing review** — https://gethumetric.com/en/docs#get-v1-metrics-pending-review

Scores the pipeline flagged as uncertain — thin evidence, conflicting signals, or confidence below the pack’s bar. This is the human-in-the-loop queue.

Required scope: `packs:admin`

Request:
```bash
curl -X GET https://api.gethumetric.com/v1/metrics/pending-review \
  -H "Authorization: Bearer hm_live_xxxx..."
```

Response:
```json
[
  {
    "entity_id": "agent-42",
    "metric_key": "tone",
    "value": 0.31,
    "confidence": 0.28,
    "source_count": 1,
    "review_status": "pending_review",
    "last_updated": "2026-08-24T19:41:02.114820Z",
    "signal_id": "e5f19c59-ac91-472a-88bf-54b75df0ddf3"
  }
]
```

Flagged metrics with their entity, current value, confidence, and why they were flagged.

Note: A flagged metric is still returned by the normal read endpoints — flagging asks for attention, it does not hide the value.

---

#### PUT /v1/metrics/{entity_id}/{metric_key}/review

**Override a metric** — https://gethumetric.com/en/docs#put-v1-metrics-entity-id-metric-key-review

Replace a score by hand when a reviewer knows better than the extractor, and record why.

Required scope: `packs:admin`

Parameters:
  - entity_id [string (path)] (required): Target entity ID
  - metric_key [string (path)] (required): The metric’s key, exactly as declared in the pack.
  - value [number] (required): The corrected value, from −1 to 1.
  - confidence [number] (required): How sure the reviewer is, from 0 to 1.
  - comment [string] (optional): Why the score was changed. Stored with the override in the audit trail.

Request:
```bash
curl -X PUT "https://api.gethumetric.com/v1/metrics/agent-42/code_quality/review" \
  -H "Authorization: Bearer hm_live_xxxx..." \
  -H "Content-Type: application/json" \
  -d '{"value": 0.8, "confidence": 0.95, "comment": "Reviewed the transcript by hand — the extractor missed the refactor"}'
```

Response:
```json
{
  "entity_id": "agent-42",
  "metric_key": "tone",
  "value": 0.6,
  "confidence": 0.95,
  "review_status": "reviewed",
  "reviewer_override": {
    "value": 0.6,
    "confidence": 0.95,
    "comment": "Customer was terse, not unhappy.",
    "api_key_id": 10,
    "at": "2026-08-24T19:52:44.019277Z"
  },
  "last_updated": "2026-08-24T19:52:44.019277Z"
}
```

The previous and new value and confidence, the comment, and overridden_at.

Note: The override is written to history like any other contribution, so the audit trail stays intact. value takes −1 to 1 and confidence 0 to 1. Later signals can still move the metric — an override is a correction, not a lock.

---

### Account

Usage, audit trail, and service health.

#### GET /v1/usage

**Usage report** — https://gethumetric.com/en/docs#get-v1-usage

Your consumption over a date range, broken down by day — signals processed, LLM tokens spent, and embeddings generated.

Required scope: `tenant:admin`

Parameters:
  - start_date [string (query)] (required): First day of the range, YYYY-MM-DD. Inclusive.
  - end_date [string (query)] (required): Last day of the range, YYYY-MM-DD. Inclusive.

  ],
  "total": {
    "date": "2026-08-01..2026-08-24",
    "signal_count": 1,
    "llm_token_count": 0,
    "embedding_count": 0
  }
}
```

A records array, one row per day, plus a total across the range.

---

#### GET /v1/usage/calls

**Per-call usage** — https://gethumetric.com/en/docs#get-v1-usage-calls

Usage broken down by call rather than by day — which client and which tool spent the tokens.

Required scope: `tenant:admin`

Parameters:
  - start_date [string (query)] (required): First day of the range, YYYY-MM-DD. Inclusive.
  - end_date [string (query)] (required): Last day of the range, YYYY-MM-DD. Inclusive.
  - group_by [string (query)] (optional): How to bucket the rows: day, client, or tool.
  - client [string (query)] (optional): Filter to one client: mcp, rest, or dashboard.
  - tool_name [string (query)] (optional): Filter to one tool name, e.g. humetric_query_entities.
  - limit [number (query)] (optional): Rows per page. Default 100.
  - offset [number (query)] (optional): How many rows to skip. Combine with limit to page.

Request:
```bash
curl -X GET "https://api.gethumetric.com/v1/usage/calls?start_date=2026-08-01&end_date=2026-08-24" \
  -H "Authorization: Bearer $HUMETRIC_API_KEY"
```

Response:
```json
{
  "records": [
    {
      "bucket": "2026-08-24",
      "client": "mcp",
      "tool_name": "humetric_query_entities",
      "call_count": 12,
      "llm_token_count": 8420
    }
  ],
  "total": { "bucket": "all", "call_count": 12, "llm_token_count": 8420 }
}
```

records with a bucket, client, tool_name, call_count and llm_token_count, plus a total.

Note: start_date and end_date are required here; omitting them returns 422. Attribution comes from optional request headers (X-HuMetric-Client, X-HuMetric-Tool), so calls made without them are grouped as unattributed.

---

#### GET /v1/audit-logs

**Audit log** — https://gethumetric.com/en/docs#get-v1-audit-logs

Who did what, when. Every write, key change, and rejected authentication attempt on your account.

Required scope: `entities:read`

Parameters:
  - action [string (query)] (optional): Filter to one action, e.g. entity.create or auth.rejected.
  - entity_id [string (query)] (optional): Filter to the entries that touched one entity.
  - limit [number (query)] (optional): Rows per page. Default 100.
  - offset [number (query)] (optional): How many rows to skip. Combine with limit to page.

Request:
```bash
curl -X GET "https://api.gethumetric.com/v1/audit-logs?action=entity.create&limit=100" \
  -H "Authorization: Bearer hm_live_xxxx..."
```

Response:
```json
{
  "items": [
    {
      "id": 55,
      "action": "consent.revoked",
      "entity_id": "agent-42",
      "details": { "scope": "health_data" },
      "api_key_id": 10,
      "created_at": "2026-08-24T19:39:30.839160Z"
    }
  ],
  "total": 2,
  "limit": 5,
  "offset": 0
}
```

items with total, limit, offset. Each row carries the action, the entity it touched, the API key that made the call, and a details object.

---

#### GET /healthz

**Health check** — https://gethumetric.com/en/docs#get-healthz

Whether the API is up. The one endpoint that needs no API key and is never rate limited.

Request:
```bash
curl -X GET https://api.gethumetric.com/healthz
```

Response:
```json
{
  "status": "ok",
  "service": "humetric",
  "version": "1.0.0"
}
```

A status object. 200 means the API is serving requests.

Note: This checks the API process only. Use it for uptime monitoring, not to tell whether your signals are being processed — a queued backlog still answers 200.

---

#### GET /healthz/db

**Database health** — https://gethumetric.com/en/docs#get-healthz-db

Whether the API can reach its database. Needs no API key.

Request:
```bash
curl -X GET https://api.gethumetric.com/healthz/db
```

Response:
```json
{
  "status": "ok",
  "database": "connected"
}
```

A status object. Anything other than "ok" means reads and writes are currently failing.

---

#### GET /healthz/worker

**Worker health** — https://gethumetric.com/en/docs#get-healthz-worker

How the background pipeline is doing: how many workers are alive, how deep the queue is, and how many signals failed in the last hour. Needs no API key.

Request:
```bash
curl -X GET https://api.gethumetric.com/healthz/worker
```

Response:
```json
{
  "workers": 1,
  "queue_depth": 0,
  "oldest_pending_seconds": 0,
  "failed_last_hour": 0
}
```

workers, queue_depth, oldest_pending_seconds, and failed_last_hour.

Note: This is the endpoint to alert on, not /healthz. The API answers 200 happily while a stalled worker leaves every signal unprocessed — a rising oldest_pending_seconds is what tells you that is happening.

## Start from a pack that already runs

A pack is just YAML. These are the packs HuMetric ships with, not illustrations — pick the closest one, send it as the yaml_text field of POST /v1/packs, then edit the metrics for your own domain. Remember the ceiling of 7 metrics.

Metric keys in the shipped packs are Turkish because the extraction prompt refers to them by name. They are identifiers, not labels: rename them if you like, but rename them in the prompt too, or the extractor will produce nothing.

## When something goes wrong

Most failures share the envelope below: the code is stable and safe to branch on, the message is for humans and may change, and doc_url points back at the row for that code on this page. Two kinds of response do NOT use it, and both are easy to miss — read the next two blocks before you write your error handling.

```json
{
  "error": {
    "code": "entity_not_found",
    "message": "Entity not found: agent-42",
    "doc_url": "https://gethumetric.com/docs/errors/entity_not_found"
  }
}
```

### Two shapes that are not that envelope

#### Request validation — 422

When the body or a query parameter fails schema validation, the framework answers before the envelope is ever built. You get a detail array instead, with one entry per offending field. A client that reads error.code will find nothing here, so check for detail as well. (The validation_error code in the table below is a different thing: it comes from checks the API runs itself, such as pack validation, and it does use the envelope.)

```json
{
  "detail": [
    {
      "type": "missing",
      "loc": ["body", "entity_id"],
      "msg": "Field required",
      "input": { "entityId": "agent-42" }
    }
  ]
}
```

#### Tier limit — 402

The billing guard answers before the request reaches a handler, and its error field is a flat string rather than an object. Branching on error.code crashes here; branch on the HTTP status instead.

```json
{
  "error": "tier_limit_exceeded",
  "message": "Free tier limit exceeded (signals: 1000/1000). Upgrade at /v1/billing/checkout.",
  "upgrade_url": "/v1/billing/checkout?tier=pro",
  "current_usage": { "signals": 1000 }
}
```

### Every code

- `validation_error` (HTTP 400 / 422): A check the API runs itself rejected the request — pack validation, or an unsupported billing tier. Schema-level failures return the detail shape above instead.
- `invalid_yaml` (HTTP 422): The pack YAML could not be parsed, or parsed to something that is not a mapping.
- `too_many_metrics` (HTTP 422): The pack declares more than 7 metrics, which is the ceiling for a single pack.
- `unknown_entity_type` (HTTP 422): No pack has ever been published for that entity_type, so there is nothing to extract against.
- `no_active_pack_for_type` (HTTP 422): A pack exists for that entity type but none is currently active.
- `missing_required_fields` (HTTP 422): The entity is missing a field the pack declares under required_fields.
- `invalid_api_key` (HTTP 401): The key is missing, malformed, revoked, or expired. Also returned when the Authorization header is absent.
- `insufficient_scopes` (HTTP 403): The key is valid but lacks the scope this endpoint requires. Also returned when creating a key that asks for scopes the creating key does not itself hold.
- `entity_archived` (HTTP 403): The entity is archived and no longer accepts signals.
- `entity_type_locked` (HTTP 403): The entity already exists with a different entity_type. An entity’s type cannot be changed after creation.
- `cannot_delete_self` (HTTP 403): A key cannot revoke itself. Create a replacement, then revoke with the new key.
- `tier_limit_exceeded` (HTTP 402): The free-tier ceiling for signals, entities, or packs is full. Upgrade to continue. Uses the flat shape shown above, not the envelope.
- `entity_not_found` (HTTP 404): No entity with that ID in your tenant. Create it before sending signals.
- `signal_not_found` (HTTP 404): No signal with that ID.
- `pack_not_found` (HTTP 404): No pack with that key.
- `metric_not_found` (HTTP 404): The entity has no value recorded for that metric key — or has one you are not allowed to read. See the note below the table.
- `api_key_not_found` (HTTP 404): No key with that id on your account.
- `pack_already_exists` (HTTP 409): A pack with that key already exists. Use PUT to update it.
- `entity_type_already_active` (HTTP 409): Another pack is already active for that entity type. Update it instead of creating a second.
- `rate_limit_exceeded` (HTTP 429): Too many requests this minute. Retry-After tells you how long to wait.
- `internal_error` (HTTP 500): Something failed on our side. Safe to retry.
- `byo_key_unavailable` (HTTP 501): This deployment has bring-your-own-key storage disabled, so tenant provider keys cannot be read or written.
- `llm_auth_failed` (HTTP 502): The configured model provider rejected our credentials. Check the provider key on your account.
- `llm_quota_exhausted` (HTTP 502): The configured model provider reports the account is out of credit or quota.
- `llm_unavailable` (HTTP 502): The configured model provider returned an error we cannot classify. Safe to retry.
- `llm_rate_limited` (HTTP 503): The configured model provider is rate limiting us. Retry with backoff.
- `ai_service_unavailable` (HTTP 503): The pack wizard could not reach a model provider. Retry shortly.
- `service_unavailable` (HTTP 503): The API could not reach its own database while authenticating the request. Retry shortly.

There is no consent_required error. A sensitive metric the caller may not read answers 404 metric_not_found, exactly as a metric that was never written would — deliberately, so that the response does not reveal that the value exists. Grant the consent scope and the same request starts returning the value.

## Rate and volume limits

Limits apply per tenant, not per key, so adding keys does not buy more throughput.

- **Requests**: 100 requests per minute per tenant, as a token bucket. Exceeding it returns 429 with a Retry-After header. /healthz is exempt.
- **Free tier**: 1,000 signals per month, 10 entities, and 1 pack. Hitting a ceiling returns 402 tier_limit_exceeded on writes; reads keep working.
- **Payload sizes**: Signal text is capped at 300,000 characters — enough for a full multi-hour transcript. Entity free_text is capped at 50,000, pack YAML at 102,400, and the pack wizard prompt at 100,000.
- **Metrics per pack**: A pack may declare at most 7 metrics; an eighth is rejected with 422 too_many_metrics. This is a quality ceiling rather than a billing one — every metric in the pack is scored on every signal, so a wide pack makes each extraction slower, costlier, and less careful about each individual metric. Split a domain across several entity types instead of widening one pack.

Every response carries your budget:

X-RateLimit-Limit: 100
X-RateLimit-Remaining: 87
X-RateLimit-Reset: 41

The API also serves the endpoints behind registration, login, tenant settings and billing (/v1/register, /v1/login, /v1/tenant/*, /v1/billing/*). Those exist for the dashboard, are not part of the integration surface, and may change without notice — build against what is on this page.
