  description: >-
    A single free API key obtained by registering at https://aisstream.io/. The
    key is placed in the `APIKey` field of the JSON subscription message sent
    over the open WebSocket (wss://stream.aisstream.io/v0/stream). It is NOT an
    HTTP header, bearer token, or OAuth flow - AISStream carries the credential
    inside the WebSocket message payload. A subscription message (with the key)
    must be sent within 3 seconds of connecting or the server closes the socket.
