# Get Observability Key Detail

`GET /observability/keys/{api_key_id}`

Drill-down for one key: daily spend/token series, model mix, harness mix, recent tasks.

## Path parameters

- `api_key_id` string, required — API key UUID to drill into.

## Query parameters

- `start_date` string, nullable — Range start (ISO date or datetime, UTC). Defaults to 30 days ago.
- `end_date` string, nullable — Range end (ISO date or datetime, UTC). Defaults to now.
- `scope` 'team' | 'personal' — ``team`` (default) aggregates the active team's coding-agent tasks; ``personal`` narrows to tasks on keys the requesting user created.

## Response `200`

Successful Response

- KeyDetailResponse — Drill-down for one API key: daily series, model / harness mix, recent tasks.
  - `api_key_id` string, required
  - `api_key_name` string, nullable, required
  - `key_creator_user_id` string, nullable, required
  - `key_creator_name` string, nullable — Display name of the team member who created the key.
  - `key_creator_email` string, nullable — Email of the team member who created the key.
  - `spend` number, required
  - `task_count` integer, required
  - `daily` KeyDailyPoint[], required
    - `date` string, required
    - `spend` number, required
    - `total_tokens` integer, required
  - `model_mix` ModelSlice[], required
    - `model` string, required
    - `spend` number, required
    - `total_tokens` integer, required
  - `harness_mix` HarnessSlice[], required
    - `harness` string, required
    - `spend` number, required
    - `task_count` integer, required
  - `recent_tasks` RecentTask[], required
    - `task_id` string, required
    - `started_at` string, date-time, required
    - `ended_at` string, date-time, required
    - `harness` string, required
    - `harness_surface` string, nullable, required
    - `category` string, nullable, required
    - `task_type` string, required
    - `request_count` integer, required
    - `spend` number, required
    - `total_tokens` integer, required
    - `models_used` string[], required
  - `meta` ObservabilityMeta, required — Data-quality envelope attached to every observability response. Lets the UI label boundaries instead of silently under-reporting: the category window (classification only runs over recent inline payloads), the per-harness payload coverage, and the earliest date harness attribution is available (before which no data exists, so a picker must not offer it).
    - `category_window_days` integer, required — Category classification only covers the last N days of inline payloads.
    - `category_window_start` string, date-time, required — UTC start of the category-classification window (now - category_window_days).
    - `coverage_start_date` string, date-time, required — Earliest UTC date with caller metadata / harness attribution; date ranges before this return nothing.
    - `harness_coverage` HarnessCoverage[], required — Per-harness category-coverage gating for UI labelling.
      - `harness` string, required
      - `coverage` 'full' | 'partial' | 'excluded', required
    - `generated_at` string, date-time, required — UTC time this response was computed.
