`data_status`How many ships are live now (live_ships_private: how many of them are private vessels, counted only), how many are known from the last 7 days, the date range of the history archive per source with available_until (the latest time vessel_track can return for that source on plans without live data), and the service status: ok or degraded, with reason codes in reasons.

No	Yes	Yes	No
`expected_arrivals`Ships that have not arrived yet at one port, from the port's own records: estimated arrival and departure (UTC), berth and declared previous port, from 6 hours ago to 14 days ahead, in arrival order. Available for Finnish ports; elsewhere the list is empty. Get the port_id from find_port. Needs an AIS Trail account (sign in when the MCP client asks, or send an API key as the HTTP header 'Authorization: Bearer ap_live_…') and a plan with live data (Pro or Business); at most 200 ships per call, 1 credit per ship returned.

No	Yes	Yes	Yes
`find_port`Find ports by name (or part of it), UN/LOCODE (e.g. FIHEL) or two-letter country code (e.g. FI) in the port reference (World Port Index and UN/LOCODE ports): id (for port_calls), name, country, UN/LOCODE, position, harbor size (World Port Index ports only) and the radius of the port area used to detect port calls. At most 20 ports, larger harbors first. No API key needed.

At most 20 ports, larger harbors first. No API key needed.	No	Yes	Yes	No
`get_vessel`Everything known about one ship now: identity (name, IMO, call sign, flag, type, size), last position, speed, course, heading, navigational status, destination (port codes decoded) and ETA as given by the crew, how long ago it was heard, its track over the last 40 minutes, and the data sources to credit. flag (ISO code) and flag_country come from the MMSI: the flag of the radio licence, usually but not always the registry flag. dwt_estimate is an estimate from the AIS dimensions (tonnes, size class such as Panamax or VLCC, hull, draught used), not a registry value; null for tugs, pleasure craft and other types where deadweight does not apply. For archive records and sanctions flags, use lookup_vessels (account).

`lookup_vessels`Records of up to 20 ships at once from the AIS Trail archive, by mmsi and/or imo (lists): identity and particulars (name, IMO, call sign, type, flag from the MMSI, length, beam, estimated deadweight, first and last seen) and sanctions flags by IMO number from three official lists: OFAC SDN, UK Sanctions List and EU Regulation 833/2014 Annex XLII (list, programmes, date listed). An IMO number resolves to the MMSI that reported it last; ships not in the plan's sources come back with found false. Sanctions flags are informational, not a compliance determination: only ships a list names by IMO number are matched, ownership-based sanctions are not covered. Needs an AIS Trail account: sign in when the MCP client asks, or send an API key as the HTTP header 'Authorization: Bearer ap_live_…'.

`search_vessels`Find ships by name (or part of it), MMSI (9 digits) or IMO number (7 digits). Returns live ships first, then ships out of range with their last known position (up to 7 days). List results are compact rows (mmsi, name, category, flag (ISO code from the MMSI), lat, lon, speed_kn, course_deg, length_m, destination, age_s, status, source); call get_vessel for full details of one ship. Private vessels (pleasure craft, sailing vessels and Class B transponders without a valid IMO number) are never listed or looked up individually; area and nearby results report how many were left out (private_vessels).

Rows: [time, event, old_value, new_value, lat, lon, mmsi, port_id, zone, sanctions, detail]; detail says more about behaviour events.

The plan's history depth, credits (as on the track endpoint: 1 per vessel-day) and rate limit apply, and the 24-hour delay on recent data on plans without live data. sources_through gives, per source, the time up to which the archive holds its data; pending_days lists days in the range a source has not delivered yet, so no points on those days does not mean the ship was absent.
