An application programming interface defines how software components interact.

supported

A client constructs a request according to the contract; routing selects an operation; the server validates identity and input, performs domain work, and returns a documented response.

supported

Contract tests, schema validation, generated documentation, mock servers, client SDKs, and integration tests verify whether implementation matches the published interface.
