Building anything with transit data — a departure screen, an app, a trip planner on your website, nearby stations for a property listing — means:
Transit is the app of choice for millions of riders every day.
For 12 years, we’ve gathered raw data for trains, buses, bikes, and more, and turned it into accurate real-time departures, sensible trip plans, and multimodal journeys.
Now you can use our APIs for your next project.

...so our data gets corrections you won't find anywhere else. Thousands of emails a year to and from transit agencies, thousands of riders flagging issues, plus continuous crowdsourced improvements from users on their commute.
