OpenAPI Specification (OAS) is a standard format for reading and describing HTTP APIs. This allows people to understand how an API works, how a sequence of APIs work together, generate client code, create tests, apply design standards, and more. Bruno allows you to work with OpenAPI Specification (OAS) files in a number of ways. Import supports both OpenAPI 2.0 (Swagger 2.0) and OpenAPI 3.x; see Import an OpenAPI Spec for details.
