REST API - Feeds

Transitland is built on publicly available GTFS data contributed by our user community to the Transitland Atlas.

Feeds contain details on how to access transit information, including URLs to data sources in various formats (GTFS, GTFS-RT, GBFS, etc), license information, related feeds, details on how to make authorized requests, and feed version archives. Feed versions are archived (as .zip files) and imported into the Transitland database for querying agencies, stops, routes, trips, etc.

Feed license information
