Community Transit API
Overview
Community Transit (Transitland) is a free, open API that aggregates public transit data from hundreds of agencies worldwide including routes, stops, and schedules. No API key is required, making it very beginner-friendly for experimenting with transit data. It is a great starting point for building transit-aware apps without worrying about authentication.
Beginner Tip
Use the Transitland API Explorer at https://www.transit.land/documentation to browse available endpoints and test queries in your browser before writing code. Start with the /routes endpoint to list transit routes by bounding box.
