Open Waters AIS

Vessels currently inside a latitude/longitude bounding box, newest report first, with optional kind and ship-type filters. Use for what is in a port, a strait, or a stretch of coast. Anonymous calls may cover 100 square degrees per call.

Vessels within a radius (default 10 NM, maximum 50) of a point or of another vessel, nearest first, each with distance and bearing from the centre. Use for what is near this position or what is around vessel X.

Where Open Waters AIS is hearing AIS right now: sources, stations, freshness, and vessel counts. Pass a bounding box to learn which stations cover it and how many vessels are in it, or a station id for that station's numbers. Call this before saying a region has no traffic.

Current position and details of specific vessels by MMSI (Maritime Mobile Service Identity): the last report heard for each, and which MMSIs have not been heard in the last 30 minutes. Use search_vessels_by_name first when you only have a name.

Vessels whose name contains the text, case-insensitive, among vessels heard in the last 30 minutes. Use to turn a name into an MMSI, then get_vessels or find_vessels_near for detail. An optional bounding box narrows the search.
