I would recommend you Sphinx, you add your documentation as __doc__ and the autodoc module of Sphinx will generate the docs for you (docs.python.org also uses Sphinx). The markup is reStructuredText, similiar to Markdown (if you prefer Markdown, you can use pdoc).

e.g.:

@app.route('/download/<int:id>')
def download_id(id):
    '''This downloads a certain image specified by *id*'''
    return ...

r/Python on Reddit: What tools do you use to auto-generate api docs in python packages?
August 22, 2023 -

Hey,

I've been lately writing Declarai, an open-source llm-related library.

The need for a clear API reference documentation came fast and I started looking for good auto-generate documentation tools.

Up until now, I found mkdocstrings the best choice as im using mkdocs anyhow.

Do you guys aware of any other great tools for api documentation auto-generation ?
