Hi @jbebic - I just got it working with that Python package, by fetching data from a FastAPI endpoint hosted on Heroku, with a Next.js app hosted on Vercel.
For me, the part that was missing from the PyPi page was the detail about adding scope to the API in the Auth0 Dashboard (had me running in circles for longer than I’d like to admit). Have you already added permissions there?
If not, it can be done by creating/navigating to your API (which is also shown as a machine to machine application in your list of applications), then clicking on your app name, going to Permissions, then adding the permission scope that you specified as per the PyPi docs, as well as a description.
Lmk if this isn’t it! Happy to look into it!
