A community-driven directory of publicly available REST API definitions in OpenAPI 2.0/3.x format, described as 'Wikipedia for Web APIs'. It curates, converts, and corrects machine-readable API specs and exposes the whole collection through a REST API and RSS feeds.

Use cases

• find openapi definitions for public apis
• download machine-readable api specs for code generation
• browse a catalog of rest apis by category
• get openapi 3.0 specs for third-party services
• feed api definitions into an api client or sdk generator
• track newly added or updated public apis

When to choose

• you need OpenAPI/Swagger definitions for many public APIs in one place
• you want machine-readable specs to generate SDKs, mocks, or documentation
• you're building an API search or catalog tool and need a data source

When to avoid

• you need definitions for private or internal APIs
• you need a single API's official, authoritative spec rather than a curated copy
• you need non-REST protocols like GraphQL or gRPC definitions
