Transit (the Transit App) is a real-time public transit trip planning and departures platform covering 1,100+ cities in 37 countries. The Transit REST API delivers real-time departures, nearby routes and stops, route details, multimodal trip planning, and service alerts, plus shared-mobility availability for bikes, scooters, and carshare. The API is publicly documented at api-doc.transitapp.com but access is key-gated - developers request a key that grants a free tier (5 requests/minute, 1,500 requests/month), and higher volumes are arranged with the partnerships team. Requests are authenticated with an apiKey header against https://external.transitapp.com/v3.
