Spire Maritime

Spire Maritime AIS TCP Stream

Always-on real-time AIS feed delivered over a RAW TCP SOCKET (not HTTP, not WebSocket). Client opens a TCP connection to streamingv2.ais.spire.com port 56784, authenticates with a token, and receives encoded AIS sentences in NMEA 0183 v4.0 with a timestamp TAG-block prefix, one sentence per line. A server-side cursor resumes the stream after brief disconnects. This is a plain TCP transport - there is NO documented WebSocket (wss://) endpoint.
