API Documentation for Anvil App

I need to write an externally facing API (preferably using anvil HTTP endpoints)
Most of the stuff I do is internal to the company where I work.

I also want to easily write documentation (preferably even using OpenAPI / SwaggerHub html) , so think this this FR would be useful.

I recently found out that FastAPI (which uses pydantic, which server modules already have installed) has a feature that automatically creates a SwaggerUI based docs page, so I’m sure its possible.
I am unsure of how easy to implement it would be, but it would make Anvil incredibly powerful for making an API with a front facing web presence, and secure internal backends to get data to serve via API (using uplink).
