Transit
Transit is a Montreal-based mobility app that provides real-time public transit, multimodal trip planning, and shared-mobility navigation across 1,000+ cities worldwide. The consumer app displays nearby buses, subways, trains, bikeshare, scooters, carshare, and on-demand transit the moment it opens, and is augmented by "GO" crowdsourced vehicle locations contributed by millions of riders. Transit operates a partner program for transit agencies, mobility operators, and third-party developers, exposing its routing, real-time, alerts, and shared-mobility surface through the public Transit API (api-doc.transitapp.com, v4 stable). The v4 API is a single OpenAPI 3.1 contract covering nearby routes and stops, stop departures, multimodal trip planning, placemarks for shared-mobility vehicles and docks, available networks, route and trip details, service alerts, and real-time vehicle positions. Authentication is an apiKey header; the free tier allows 5 requests per minute and 1,500 calls per month after key approval, with custom commercial plans available through partners@transit.app.
Transit publishes 3 APIs on the APIs.io network: Map Layers API, Public API, and Vehicles API. Tagged areas include Transit, Public Transit, Multimodal, Mobility, and Trip Planning.
Transit’s developer surface includes authentication, developer portal, documentation, engineering blog, tooling, and 26 more developer resources.
