Activity API



For Use By: Third-party developers can use the API to build applications to distribute events and activities from the database.

The Activity APIs give developers easy access to's broad array of activity data. It is centered around the concept of "assets", where events, races, tournaments, facilities, classes, leagues are all considered assets. Each asset has a unique ID, and data about a given asset can be retrieved with this ID.

With the Activity Search API, developers can search for all half marathons coming up over the next few months in San Diego, California. Or they can get a list of tennis tournaments happening in New York over the summer. They can dive in to get detailed information about the Bay to Breakers, including the event director's race description, latitude and longitude for the starting point of the race, and fees. And after the Bay to Breakers happens, the APIs can be used to query user reviews of the race.

All of the APIs are read-only and return public data. As a result, no security measures (SSL, Oauth) are required. Race registrations are done online on

    Thanks for this API information. I was stuck in the coding and this API helps me a lot to complete my project. Especially for working on this project, I bought a new laptop from Reecoupons.
