MBTA-realtime Developer Portal

Welcome to the API-V2 and MBTA-performance API portal. Here you can obtain and manage API keys for API-V2 and the MBTA-performance APIs.

Attention API-V2 users: API-V2 is now deprecated. The MBTA will continue to operate API V2 feeds through April 2018 and makes no commitment to operation after that. Developers should migrate to the V3 API or GTFS-realtime. The MBTA-performance API is not deprecated.

All MBTA developer documentation can now be found at our MBTA developers documentation page.
