latestOpenAPI 3.0.32026-07-226744340.8 KBChokepoint transit activity
Hourly vessel-flow rollup for maritime chokepoints, derived from terrestrial AIS. Each row is one chokepoint·hour with vessel counts and average speed. Requires a plan with Maritime intelligence access (can_use_maritime) — the Corporate & Supply Chain plan and above.
Forward-accruing: signals begin at launch (June 2026) — there is no historical backfill. Derived-only: no raw position track is exposed. Terrestrial AIS only (no satellite). Date windows are capped at 30 days; defaults to the trailing 7 days when no dates are given.
Query parameters
Restrict to one chokepoint (one of the 11 monitored straits). Omit for all.
Window start YYYY-MM-DD (≤30-day window).
Window end YYYY-MM-DD.
Trailing N-day window (1–30). Defaults to 7.
Rows per page (1–500).
Pagination cursor (offset) from a prior response's next_cursor.
Response
A page of chokepoint·hour rows, most recent first. Each row: chokepoint, hour, vessels, moving_vessels, avg_sog (average speed over ground, knots), positions (AIS message count). Standard envelope: { success, data, pagination, applied_filters }.
