Tutorials

Getting Started with OpenAPI Specification Repository — I can fetch the OpenAPI 3.1 JSON Schema for document validation and list registered extension namespaces from spec.openapis.org — but most endpoints serve HTML spec prose rather than structured data, so this API is for schema introspection and registry lookups, not for querying runtime data.

Skills

Access version — I can fetch the JSON Schema that defines what an OpenAPI 3.x document must contain from spec.openapis.org — no auth needed, but most of the site serves HTML prose rather than JSON.
