# AIS-dark gaps

`GET /api/v2/maritime/gaps`

AIS-dark gaps — intervals where a vessel stopped broadcasting AIS then reappeared, derived from terrestrial AIS coverage. Each row is one gap with the last-known position before it went dark. Requires a plan with Maritime intelligence access (`can_use_maritime`) — the Corporate & Supply Chain plan and above.

Forward-accruing: gaps begin accruing at launch (June 2026) — no historical backfill. Terrestrial AIS only (no satellite); a gap reflects loss of terrestrial reception, not necessarily a deliberate dark event. Filtered by gap-end time; date windows are capped at 30 days and default to the trailing 7 days.

## Query parameters

- `chokepoint` 'hormuz' | 'bab_el_mandeb' | 'malacca' | 'suez' | 'panama' | 'bosphorus' | 'gibraltar' | 'dover' | 'kerch' | 'taiwan' | 'danish_straits'
- `min_gap_hours` number
- `date_start` string
- `date_end` string
- `days` integer
- `limit` integer
- `cursor` string

## Response `200`

A page of AIS-dark gaps, longest first. Each row: imo, mmsi, gap_start, gap_end, gap_hours, last_lat, last_lon, chokepoint (last-known before going dark). Standard envelope: { success, data, pagination, applied_filters }.
