Transportation — entry 053 of 69
Transport for Philadelphia, US
SEPTA's real-time data is spread across a family of small JSON endpoints under www3.septa.org/api (TrainView, TransitView, NextToArrive, Alerts, BusDetours) plus separate GTFS-RT protobuf feeds, and is now indexed through a Swagger UI at api.septa.org rather than the old Code-for-America hackathon reference page. None of the endpoints tested require a key, but SEPTA doesn't publish rate limits or uptime guarantees.
