OneBusAway

description: >-
  OneBusAway is an open-source real-time transit information platform managed
  by the Open Transit Software Foundation. It provides transit riders with
  real-time arrival predictions, service alerts, and schedule data for buses,
  trains, and other transit modes. The platform exposes a RESTful API that
  lets developers access agency information, stop data, route details, trip
  information, real-time arrivals and departures, vehicle positions, and
  service alerts. Authentication uses an API key passed as a query parameter.
  The reference deployment runs at api.pugetsound.onebusaway.org; many transit
  agencies host their own OneBusAway instances using the same API contract.
  Official SDKs are published for Go, Java, Kotlin, JavaScript/Node.js,
  Python, and Ruby, all generated from a shared OpenAPI 3.0 specification in
  the sdk-config repository.

    description: >-
      RESTful web service providing real-time and scheduled transit data for
      agencies running the OneBusAway platform. Endpoints cover agencies with
      coverage, individual agency details, routes, stops, trips, real-time
      arrivals and departures, active vehicle positions, schedule information
      for stops and routes, shape/polyline data, block configuration, search
      for stops and routes by location or name, and user-submitted problem
      reports. Authentication is an API key supplied as the "key" query
      parameter. Responses are available in both JSON and XML; JSON responses
      support an optional JSONP callback parameter. The reference server is
      the Puget Sound deployment at api.pugetsound.onebusaway.org; transit
      agencies can self-host using the open-source application modules.
