Spire Maritime AIS TCP Stream is one of 5 APIs that [Spire Maritime](https://apis.io/providers/spire-maritime/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Real-Time Data, Streaming, AIS, NMEA 0183, and TCP. The published artifact set on APIs.io includes API documentation.

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.
