Question 4

How do I search for vessels in a specific area?

Accepted Answer

Use the /api/v1/vessels/area endpoint with bounding box coordinates (min_lat, min_lon, max_lat, max_lon) or the /api/v1/vessels/vessel_inradius endpoint with a center point and radius in kilometers to find all vessels within a geographic area.

Question 5

What is AIS and how does vessel tracking work?

Accepted Answer

AIS (Automatic Identification System) is a maritime safety system where ships broadcast their position, speed, heading, and identity via radio. Poseidon aggregates these AIS signals globally and makes them available through a developer-friendly REST API with sub-200ms latency.
