## What it is
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

## Facets
- artifact type: dataset
- maturity: active
- function: api-framework, documentation, search-engine
- domain: apis, developer-tools, documentation, web-development
- platform: cli, cross-platform
- tags: openapi, swagger, api-directory, api-catalog, rest-api, open-data, machine-readable-definitions, web-server
