sphinxcontrib-openapi is a Sphinx extension to generate APIs docs from OpenAPI (fka Swagger) spec. It depends on sphinxcontrib-httpdomain that provides an HTTP domain for describing RESTful HTTP APIs, so we don't need to reinvent the wheel.

$ python3 -m pip install sphinxcontrib-openapi

Pass sphinxcontrib-openapi to extensions list in Sphinx's conf.py

extensions = [
   ...
   'sphinxcontrib.openapi',
]

and feel free to use the openapi directive to render OpenAPI specs

.. openapi:: path/to/openapi.yml
