# One vessel's track over time

`GET /api/v2/maritime/vessels/{imo}/track`

⚠️ RAW position track for a single vessel by IMO — the literal 'this ship over time': every AIS fix (time, position, speed, course, heading, nav status) across the window, time-ordered. Keyset-paginated: follow the opaque next_cursor to stitch a long window into pages rather than one giant response. Requires a plan with Maritime intelligence access (`can_use_maritime`) — the Corporate & Supply Chain plan and above.

Historical / baseline surface: reads raw AIS positions directly. Forward-accruing: positions begin at launch (June 2026) — no historical backfill. Terrestrial AIS only (no satellite). Date windows are capped at 30 days; defaults to the trailing 7 days.

## Path parameters

- `imo` string, required

## Query parameters

- `date_start` string
- `date_end` string
- `days` integer
- `limit` integer
- `cursor` string

## Response `200`

A page of the vessel's raw position track, time-ordered ascending. Envelope: { success, imo, data, pagination, applied_filters }. Each data row: time, mmsi, lat, lon, sog, cog, heading, nav_status, chokepoint. pagination.next_cursor is an opaque token — follow it to page through a long window.
