Transit publishes 7 APIs on the APIs.io network, including Alerts API, Departures API, Mobility API, and 4 more. Tagged areas include Public Transit, Real-Time, Trip Planning, Multi-Modal, and GTFS.

The Transit catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Transit’s developer surface includes authentication, documentation, GitHub presence, engineering blog, support, pricing, signup flow, and 9 more developer resources.
