I present to you
Flask-Authlib-Client, a flask extension for authlib that answers the question "How do I validate tokens from a different resource server?". I haven't managed to publish it on Pypi because I'm having issues with my pypi account. Hoping to get it sorted soon.
Check it out on Github.
Happy New Year!
Finally got my pypi account back (yeepie!). You can now install the extension with:
pip install Flask-Authlib-Client
