An AI endpoint is a public URL that returns structured data for software to consume. A publisher might expose a manifest, catalog, sitemap, or health response as JSON.

Some machine-readable interfaces use established standards, while many files described as AI endpoints follow a publisher-defined contract. Their usefulness depends on accurate data, documentation, versioning, and a consumer that understands the contract. The filename alone does not create a ranking or citation advantage.

See AI Endpoints Explained for the distinction between standards, proposals, and custom JSON contracts.
