May Mobility Fleet Realtime API is one of 2 APIs that [May Mobility](https://apis.io/providers/may-mobility/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include Telemetry, Streaming, WebSockets, Autonomous Vehicles, and Fleet Management. The published artifact set on APIs.io includes API documentation, a getting-started guide, an API reference, authentication docs, and a changelog.

A WebSocket streaming API that delivers live May Mobility vehicle data in two modes. Telemetry mode streams JSON messages for a comma-separated list of per-vehicle topics (GPS, POSE, DRIVE_STATUS, RUNLEVEL, COLLISION_NOTIFICATION, TRAFFIC_LIGHT and others) using the topic form /.vehicle.{vehicleID}.{topicName}, with a documented ceiling of 20 topics per connection. Video mode streams exterior camera feeds for up to four vehicles per connection as serialized protobuf (quic_wrapper wrapping May.image_t, mostly VP9). Authentication is an AWS Cognito client-credentials access token passed as a token query parameter. Access is provisioned by the May Mobility Fleet API team; the connection domain is issued per account and is not published.
