How this service works
Look up vessels in the US Coast Guard PSIX registry by name (partial match), call sign, official number, hull number (HIN), flag country, service type, or build year. Returns matching vessels with the USCG vessel id, name, call sign, service type, build year, status, official number, HIN, and flag. Keyless, public-domain. Covers US-flagged vessels (and foreign vessels with US port-state-control activity). Pair the returned vesselId with maritime.cases for the inspection record. (Cross-references trade.locode for ports.)
Output
Returns a JSON array of matching vessels with fields: vessel name, USCG vessel ID, official number, hull number (HIN), call sign, flag country, service type, build year, and active status — plus source attribution with license and provider URL from the U.S. Coast Guard PSIX database.
Example use cases
Example prompt
“Can you look up the USCG vessel registry for a recreational boat with hull number SSUR4095C999 and tell me its official status, registration number, and flag?”

Endpoint
GEThttps://2s.io/api/maritime/vessel?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative, ground-truth vessel registration data from the U.S. Coast Guard public records database. Ideal for verifying vessel ownership, checking hull identification numbers, confirming active status of a boat, or researching vessels by flag country or service type. Prefer this over commercial marine databases when you need official USCG-sourced data at minimal cost with no API key required.
