What it checks

The Maritime & Port Security API provides vessel search by name, IMO number, or MMSI, with details including flag state, vessel type, gross tonnage, owner, and registration port. Also includes C-TPAT (Customs-Trade Partnership Against Terrorism) partner search to verify certified importers, carriers, and brokers. The vessel and C-TPAT data are a small development sample, labelled provenance "seed" in every response: no live vessel feed and no USCG PSIX, MarineTraffic or CBP SVI connection exists, so a vessel or partner that is not in the sample is simply not found.

Vessel search by name, IMO number, MMSI, flag state, or vessel type (sample data only)
Vessel details: gross tonnage, year built, owner, port of registry
IMO number lookup; the seven-digit check digit is validated (verified)
C-TPAT partner search by name, SVI number, or tier (sample data only)
C-TPAT certification status, tier level, and expiration date
Entity type classification: Sea Carrier, Importer, Customs Broker, etc.
