AISStream AIS Stream API
Real-time global AIS vessel-tracking stream delivered over a single WebSocket at "wss://stream.aisstream.io/v0/stream". The client connects, sends a JSON subscription message (APIKey plus BoundingBoxes and optional FiltersShipMMSI and FilterMessageTypes), and receives a continuous feed of AIS messages - each an envelope with MessageType, a free-form MetaData object, and the decoded Message keyed by its type (PositionReport, ShipStaticData, and the rest of the ITU-R M.1371 message set).
AISStream AIS Stream API is published by AISStream on the APIs.io network, described by an AsyncAPI event-driven specification.
Tagged areas include AIS, Vessel Tracking, WebSocket, Streaming, and Real-Time Data. The published artifact set on APIs.io includes API documentation, an API reference, an AsyncAPI specification, and SDKs.
This event API exposes 2 operations across 1 channel, and defines 7 schemas. It is described by AsyncAPI 2.6.0, at version 1.0.0.
The API connects through a single server, stream.aisstream.io/v0/stream (wss).
