What is the Swagger Spec Generator?

OpenAPI specs power Swagger UI, code generation, and contract testing — but writing YAML by hand is painful. List your endpoints (method, path, purpose, fields) and the AI produces a valid OpenAPI 3.0 document with schemas, parameters, and response codes that renders directly in Swagger UI.

Frequently Asked Questions (FAQ)
