**APIs profiled:** 12

RevenueCat provides in-app subscription and purchase infrastructure for mobile and web apps. It abstracts App Store, Google Play, Amazon, Stripe, Roku, and Paddle billing behind cross-platform SDKs and a REST API, handling receipt validation, entitlements, subscriber state, offerings and paywalls, experiments, and subscription analytics. A v1 REST API manages live subscribers and purchases; a v2 REST API manages the project catalog (projects, apps, products, entitlements, offerings, packages); webhooks stream subscription lifecycle events.
