API | No or Empty responses

Some of the most common reasons for receiving no data/empty responses from your API calls are:

No record in the MarineTraffic database during the defined timespan

  • You can try to alter the timespan (be careful not to exceed the upper timespan limit of each API call).

No terrestrial coverage in the area

  • The vessel(s) sails in an area with limited coverage from terrestrial AIS-receiving Stations. Consider upgrading your service to also include satellite coverage.

The actions mentioned are applicable to the following API Services:

PS02 - Vessel Positions

PS03 - Vessel Positions of a MarineTraffic Fleet

PS04 - Vessel Positions within a Port

PS05 - Vessel Positions in a Predefined Area

PS06 - Vessel Positions in a Custom Area
