description: 'May Mobility is an American autonomous vehicle technology company headquartered
  in Ann Arbor, Michigan, founded in 2017 by Edwin Olson, Alisyn Malek and Steve Vozar.
  It develops and operates self-driving shuttle, microtransit and robotaxi services
  in partnership with cities, transit agencies, commercial sites and ride-hail networks
  including Uber and Lyft, using a proprietary Multi-Policy Decision Making (MPDM)
  autonomy stack. For fleet partners May Mobility publishes a Fleet API at docs.maymobility.com
  consisting of a Realtime API (WebSocket streaming of vehicle telemetry topics and
  exterior camera video, the latter as serialized protobuf) and a Batch REST API that
  returns historical telemetry, LiDAR ROSBAG exports, vehicle shift timings and last-active
  status. Access is provisioned per account by the Fleet API team and authenticated
  with AWS Cognito OAuth 2.0 client-credentials tokens. May Mobility also operates
  its own autonomous system (AS398351) with a public NOC documentation site, peering
  policy, responsible-disclosure program and internal PKI.'

  name: May Mobility Fleet Realtime API
  description: '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.'

  name: May Mobility Fleet Batch (REST) API
  description: 'A REST API that returns historical May Mobility vehicle data between
    two Unix timestamps. Telemetry is retrieved per vehicle and topic at
    /vehicles/{vehicleID}/topics/{topicName} with startTime and endTime parameters,
    paginated in 30-second pages via an opaque metaToken carried on subsequent
    requests. Discovery endpoints list available vehicles (/vehicles) and the topics
    available for a vehicle (/vehicles/{vehicleID}/topics). Additional endpoints
    return LiDAR exports as ROSBAG files (/lidar plus a /download step), vehicle shift
    windows (/shift-timing) and vehicle last-active timestamps (/last-active).
    Documented limits: a maximum 10-minute request window, a 7-day retention window,
    no current-day data, and 5-day LiDAR log retention. Authentication is a bearer
    AWS Cognito access token issued with a batch-specific scope.'
