APIs.guru
APIs.guru is a directory of machine-readable OpenAPI and Swagger definitions for thousands of public web APIs. Callers can list every API in the directory, look up all versions published for a given provider, retrieve the metadata and hosted specification URL for a specific API version, list the providers covered, and download the full directory index in one request. Useful for API discovery and for feeding spec-driven tooling. No credentials required.
