TransportAPI provides managed services for accessing and publishing UK transport data through APIs. Its Journey Planner covers bus, train, metro, coach, tram, light rail, cycle, car, ferry, and taxi journeys across Great Britain. Bus Information and Rail Information provide nationwide scheduled and real-time data through APIs or GTFS. Managed services monitor data quality and send errors to data vendors for correction at source. API options include polling and streaming, with RESTful JSON and, for some services, Websocket JSON-RPC. Journey Planner engine choices include SilverRail, TfL API, OTP, R5, OSRM, CycleStreets, and TaxiCode. Bus Information draws on UK datasets including TNDS, BODS, NaPTAN, BODS SIRI VM, and Traveline Nextbuses SIRI SM. The services are intended for apps, websites, transport analytics, and data mining. TransportAPI says customers can use data as they see fit and that it retains no downstream rights in customer-created or developed work. The free plan costs nothing and allows 30 API hits per day, free forever.
