FleetMon

FleetMon Vessel Positions API (Retired)

Retired. AIS position tracking surface of the FleetMon API - latest vessel position (GET /vessel/{vessel_id}/position/), positions with extended vessel data for your fleet (GET /myfleet/), historical AIS track reports (GET /ais/position/), historical AIS static and voyage messages (GET /ais/static/), dynamic AIS data, vessels inside a bounding box (GET /regional_ais/), and vessels near a position (GET /vessel/near/). Endpoints are grounded in the archived Swagger 2.0 definition but are no longer live - live AIS feeds now ship as Kpler AIS via the MarineTraffic API portfolio.
