Swagger

Swagger is a suite of tools for API developers from SmartBear Software and a former specification upon which the OpenAPI Specification is based for designing, building, documenting, and consuming RESTful APIs. The specification itself is now called OpenAPI Specification (OAS). Swagger's open-source tooling usage can be broken up into different use cases: development, interaction with APIs, and documentation. Swagger is specifically for REST APIs, not for SOAP or GraphQL. It maps HTTP methods (GET, POST, PUT, DELETE) to API resources. https://en.wikipedia.org/wiki/Swagger_(software)
