Transport for London API

healthy 4,133 Subscribers

London public transport as an API, powered by the official Transport for London Unified API. Get live line status for the Tube and every other mode (DLR, Overground, Elizabeth line, trams, buses, river bus) with severity and disruption reasons, search any station or stop by name to get its NaPTAN id, modes, lines and coordinates, pull live arrival predictions for a stop (which line, to where, in how many minutes, from which platform), check a single line in detail with its current disruptions, and plan a door-to-door journey between two places with full leg-by-leg directions and durations. Stops and journey endpoints accept a place name, a NaPTAN id or lat,lon. Perfect for commuter and travel apps, station departure boards, status widgets, Slack/Discord bots and trip planners. No accounts, no upstream key.

Swiss Transit API

Switzerland's public-transport timetable as an API, powered by the official Swiss open transport service (transport.opendata.ch, built on the search.ch timetable). One of the densest and most punctual transit networks in the world — trains (SBB/CFF/FFS), trams, city and postbuses, boats, funiculars and cable cars — in a single clean API. Find stops, stations and addresses by name with their identifier and coordinates; plan a complete door-to-door journey between any two places with optional via stop, date and time and the option to search by arrival time, getting each connection's departure and arrival times and platforms, total duration in minutes, the number of transfers, the transport products used (for example IC 8 or S 8) and the full leg-by-leg breakdown including any walking sections; and read a station's live departure or arrival board with the line, destination, time, platform and any real-time delay. Ideal for journey-planner and mobility apps, travel tools, logistics and tourism in Switzerland. Place names accept stop names or station ids from the locations endpoint, and times include live delays where available. Data from transport.opendata.ch (Swiss open transport data); covers Switzerland and immediate cross-border connections.
