We've committed to making our open data freely available to third parties and to engaging developers to deliver new products, apps and services for our customers.
Over 17,000 developers have registered for our open data, consisting of our unified API (Application Programming Interface) that powers over 600 travel apps in the UK with over 42% of Londoners using apps powered by our data.
This enables millions of journeys in London each day, giving customers the right information at the right time through their channel of choice.
