# Event statistics

`GET /api/v1/gfw/events/stats`

Aggregated event statistics. Shows total counts, duration, and breakdowns by flag state and gear type for a given event type and date range.

## Query parameters

- `type` string — Event type: fishing, encounter, loitering, port_visit.
- `start_date` string — Start date (YYYY-MM-DD). Default: 90 days ago.
- `end_date` string — End date (YYYY-MM-DD). Default: today.

## Response `200`

Aggregated event statistics broken down by flag state and gear type.

- EnvelopeGfwEventsStatsData
  - `data` GfwEventsStatsData, required
    - `event_type` string, required — Event type classifier.
    - `date_range` DateRange, required
      - `start` string, required — Start date (YYYY-MM-DD).
      - `end` string, required — End of the data range or time window.
    - `stats` GfwStats, required
      - `numEvents` integer, required
      - `numFlags` integer, required
      - `numVessels` integer, required
      - `flags` string[], required
      - `timeseries` Timesery[], required
        - `date` string, required — Observation date (YYYY-MM-DD).
        - `value` integer, required — Numeric or string value.
  - `meta` SugraMeta, required — Metadata attached to every /api/v1/* response envelope.
    - `endpoint` string, required — Requested endpoint path.
    - `data_time` string, required — ISO 8601 UTC timestamp of the source data, not of the request.
    - `response_time` string, required — ISO 8601 UTC timestamp when this response was produced.
    - `provider` string, required — API name and version.
    - `source` string, nullable — Identifier of the primary upstream source used for this response.
    - `attribution` string, nullable — Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization). Present only on responses whose source requires the owner and source to be clearly identified. Do not remove or alter it when using the response.
    - `fallback_used` boolean, nullable — True when the primary source failed and a fallback produced the data.
    - `fallback_chain` string[], nullable — Ordered list of sources attempted, in the order they were tried.
    - `cached` boolean, nullable — True when this response was served from the internal cache.
    - `stale` boolean, nullable — True when the cached response was returned after the upstream rate-limited or errored. Clients can use this to detect degraded data.

## Other responses

- `401` — Missing or invalid `x-api-key` header. JSON body with a stable `code` distinguishing `missing_api_key` (no header sent) from `invalid_api_key` (header sent, key not accepted); any other 401 source carries the generic `unauthorized` with its detail as `reason`. Plus `hint`. `plan` is always null on 401 - an unauthenticated request has no plan; quota exhaustion is 429, not 401.
- `422` — Validation Error
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
