How this service works
Live AIS position, speed, heading and voyage status (destination, ETA, draught) for one vessel by 9-digit MMSI, from Finland's Digitraffic AIS feed. Covers Finnish and Baltic waters only, not global coverage; vessels outside that area return no position.
Output
A JSON object containing the vessel's MMSI, name, call sign, ship type, current latitude and longitude, speed in knots, course and heading in degrees, navigational status code, position timestamp, destination port, raw ETA value, draught in meters, the Digitraffic source URL, and the time the data was checked and last updated.
Example use cases
Port arrival monitoring for Baltic cargo
“Check the live position and ETA for the vessel with MMSI 230982000 — I need to know if it's still on course for Helsinki and what its current speed is.”
Vessel draught check before harbor entry
“What's the current draught and navigational status of the ship with MMSI 230940690? I need to confirm it's within limits before it enters the port.”
Real-time fleet position update
“Pull the latest AIS position and heading for MMSI 230001234 — I'm tracking it through the Gulf of Finland and need its coordinates and course right now.”

Endpoint
GEThttps://api.tradeenergy-api.workers.dev/api/logistics/vessel-tracker?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time AIS vessel tracking specifically within Finnish or Baltic waters and have a 9-digit MMSI identifier. It is ideal for logistics workflows, port operations, or shipping monitoring in the Gulf of Finland or Baltic Sea region. Do not use it for global vessel tracking — vessels outside Finnish/Baltic coverage will return no data.
Side effects
- Vessel outside Finnish/Baltic coverage area returns no position data
- Invalid or non-9-digit MMSI returns an error or empty result
- Vessel not currently transmitting AIS returns stale or missing data
- Unknown MMSI (vessel not in Digitraffic registry) returns null or error
- Upstream Digitraffic feed outage causes timeout or empty response
