Tools (6)

`find_vessels_in_area`read-only	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.
`find_vessels_near`read-only	Vessels within a radius (default 10 NM, maximum 50) of a point or of another vessel's last known position, nearest first, each with distance and bearing from the centre. Use for what is near this position or what is around vessel X.
`get_coverage`read-only	Where Open Waters AIS is hearing AIS right now: sources with their current delay, 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. Vessel counts cover the last 30 minutes; max_age widens them, to 7d for the last week or all for every vessel the network has heard. Call this before saying a region has no traffic.
`get_vessels`read-only	Last known position and particulars of specific vessels by MMSI (Maritime Mobile Service Identity), or by IMO number with a feeder or partner token: the last report heard for each, however long ago, with destination, ETA, draught, and dimensions once its static data has been heard, and which identifiers match no vessel the network has heard. A vessel whose IMO number has a Wikidata item also carries its type, builder, year built, tonnage, registered dimensions, registry, home port, owner, operator, former names, and Wikipedia and Commons links from there, and a documented US vessel its service type, status, official number, registered dimensions, and tonnage from the US Coast Guard. Use search_vessels_by_name first when you only have a name.
`get_vessel_track`read-only	The positions heard from one vessel over a time range, oldest first, with speed, course, and navigational status. Positions implying an impossible speed for the vessel are left out. Use for where a ship was yesterday, when it left port, or its route today. Give the vessel's mmsi, or its imo with a feeder or partner token. A call covers up to a year. By default the track is simplified by shape: the positions that hold its path, with breaks where the vessel went unheard; interval_minutes asks for even spacing instead.
`search_vessels_by_name`read-only	Vessels whose name contains the text, case-insensitive, among every vessel the network has heard, each with its last known position. Use to turn a name into an MMSI, then get_vessels or find_vessels_near for detail. An optional bounding box narrows the search. With a feeder or partner token, text of the form IMO 9241061 finds the vessels reporting that IMO number, and a bare seven-digit number finds them ahead of the name matches.
