WMATA is the Washington Metropolitan Area Transit Authority, which operates public transit in the Washington, D.C. region. It publishes developer access to transit data including rail and bus schedules, real-time predictions, and service incident information.
WMATA exposes five documented REST APIs for bus routes/stops, bus predictions, incidents, rail station data, and rail predictions; all require a WMATA API key and the published Swagger specs indicate the key can be sent either in the `api_key` header or `api_key` query parameter.
