# Chokepoint dwell episodes

`GET /api/v2/maritime/dwell`

Dwell episodes — completed arrival→departure stays at maritime chokepoints, derived from terrestrial AIS. Each row is one vessel's stay with its dwell duration. Requires a plan with Maritime intelligence access (`can_use_maritime`) — the Corporate & Supply Chain plan and above.

Forward-accruing: episodes begin accruing at launch (June 2026) — no historical backfill. Derived-only: no raw position track. Terrestrial AIS only (no satellite). Filtered by departure 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'
- `status` 'ongoing' | 'completed'
- `date_start` string
- `date_end` string
- `days` integer
- `limit` integer
- `cursor` string

## Response `200`

A page of dwell episodes, by departure time (most recent first). Each row: imo, mmsi, chokepoint, arrival, departure, dwell_hours. Standard envelope: { success, data, pagination, applied_filters }.
