AIS Tracking
& Maritime Data API

Query live vessel positions, detailed vessel profiles, emissions data, port events, and marine casualty records through a RESTful JSON API. Integrate maritime intelligence into your stack with simple HTTP requests, built for trade analytics and fleet monitoring.

AIS Vessel Positions

Latitude, longitude, SOG, course, heading, and nav status. Updated continuously from terrestrial AIS receivers (coastal & port areas).

Vessel Notifications

Vessel Notifications

Webhook and WebSocket notifications for port arrivals, departures, ETA changes, speed changes, and geofence events, checked every few minutes. Subscribe to vessel changes automatically.

Coverage

Positions come from terrestrial AIS, so coverage is strongest in coastal waters and around busy ports, and weaker or absent in open ocean and some regions. Try the free tier on the areas you need.
