RapidAPI
The world's largest API marketplace for finding and monetizing APIs.
About
RapidAPI is the largest API marketplace, aggregating tens of thousands of public APIs that developers can discover, test and subscribe to from a single account with one API key. Listings expose latency, uptime and popularity metrics, and endpoints can be tried from the browser before subscribing.
For API providers it is a distribution and monetization channel: every listing gets quota and billing plumbing through RapidAPI's gateway, which takes a 25% commission on transactions according to a 2026 analysis. The company also offers RapidAPI Studio for designing and publishing APIs, plus a white-labeled Enterprise Hub for internal API governance. Community sources put its developer base at tens of millions, though exact figures are vendor-reported and change over time.
