# Single vessel by MMSI (Northern Europe regional near-live)

`GET /api/v1/maritime/vessels/{mmsi}`

> **Deprecated.**

Look up one vessel's latest known position by MMSI within the Northern Europe regional near-live snapshot (Baltic + Norway). Scans both regions when region is omitted. Regional coverage only, bounded to these waters on a 5-minute cadence. AIS is self-reported. Returns 404 when the MMSI is not present in the current snapshot.

## Path parameters

- `mmsi` string, required — 9-digit MMSI.

## Query parameters

- `region` 'baltic' | 'norway' — Restrict the scan to one region; omit for both.

## Response `200`

Single vessel record with attribution, or 404 when not found.

- EnvelopeAisVesselData
  - `data` AisVesselData, required — Payload for GET /maritime/vessels/{mmsi}.
    - `vessel` AisVesselRecord, required — Normalized AIS vessel record (contract VesselRecord). Self-reported AIS; positions may be spoofed or stale - posture is as-is. Optional fields are null when the source omits them (never 0, never invented).
      - `mmsi` integer, required — Maritime Mobile Service Identity (9 digits).
      - `lat` number, required — WGS84 latitude.
      - `lon` number, required — WGS84 longitude.
      - `sog` number, nullable — Speed over ground (knots). Null if absent.
      - `cog` number, nullable — Course over ground (degrees). Null if absent.
      - `heading` integer, nullable — True heading (degrees). Null if absent.
      - `navstat` integer, nullable — AIS navigational status code. Null if absent.
      - `ship_type` integer, nullable — AIS ship-and-cargo type code. Null if absent.
      - `name` string, nullable — Vessel name (from static-vessels join). Null if absent.
      - `timestamp` string, required — Position report time, ISO 8601 UTC.
      - `source` string, required — In {fintraffic, kystverket}.
      - `region` string, required — In {baltic, norway}.
    - `sources` AisAttribution[], required — Provenance objects (always present).
      - `source` string, required — Human-readable source label.
      - `license` string, required — License short name.
      - `license_url` string, required — Canonical license deed URL.
      - `attribution_text` string, required — Exact credit string to surface.
      - `modified` boolean, required — True when Sugra transforms the data.
      - `original_url` string, required — Link back to the upstream source page.
    - `coverage_label` string — Honest coverage label.
  - `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.
- `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.
