Steps

  1. Register a free account at developer.wmata.com and subscribe to the Default Tier to get an API key
  2. Call the rail predictions endpoint (StationPrediction) for next-train arrival estimates by station code
  3. Call the bus predictions endpoint (NextBusService) for next-bus arrival estimates by stop
  4. Pull rail station/line topology and elevator/escalator/service-alert data from the corresponding Metro Transparent Data Sets endpoints
  5. Alternatively consume WMATA's published GTFS/GTFS-Realtime feeds if you need standard-format schedule and vehicle data instead of the proprietary REST endpoints
