Does FastAPI support Swagger (OpenAPI) version 2.0 or just 3.0 of the spec?

Does FastAPI support Swagger (OpenAPI) version 2.0 or just 3.0 of the spec?

For example, https://bravado.readthedocs.io/en/stable/, supports only version 2.0.

From what I can see in the code, it only supports 3.0.2

fastapi/fastapi/applications.py

Line 56 in ba10838

self.openapi_version = "3.0.2"

@EricG-Personal yes, it only supports the latest, OpenAPI 3.x.

If you don't want to use plain requests you can generate a client with: https://github.com/OpenAPITools/openapi-generator#openapi-generator-online-docker-image

I see that Bravado generates a client with methods live, without code generation. That probably means that it can't have any "static" type checking (in your editor, before running the code), auto-completion or documentation.

Thanks @madstacks for your help here!
