MBTA-realtime Developer Portal

Welcome to the MBTA-realtime developer portal. MBTA-realtime is the MBTA's premier alert and real-time information interface for third-party developers.

As of June 4, 2013, MBTA-realtime alert and schedule data is live and in production. Real-time commuter rail and subway data to follow at a later date. Other data remains available on the general MBTA Developers Page.

Getting started is as easy as 1, 2, 3.

  1. Take a look at the documentation to learn what’s available and how it works.

  2. Register for a developer account for yourself and an API key for each app.
    (Getting a key may take a day, but you can try out the API with the open development key while you wait.)

  3. Published an app? We’d love to tell people about it, so submit it to our App Showcase! (Done something else cool with the data? We’d love to hear about it.)

    Simple, right? If not, help is available.
