USCG Port State Information Exchange API

The U.S. Coast Guard (USCG) Port State Information Exchange (PSIX) is an information system containing vessel-specific information on U.S. flag vessels, foreign flag vessels operating in U.S. waters, and contacts with those vessels. This information is derived from the Marine Information Safety and Law Enforcement System (MISLE). PSIX information can be accessed directly through the USCG website or programmatically via SOAP API.
