Auth0 Fastapi Api

This is Auth0's official SDK wrapper for protecting FastAPI REST endpoints with JWT access token validation. You'd reach for this when building an API that needs to validate tokens from SPAs, mobile apps, or service-to-service calls. It handles the JWKS ceremony, scope checks, and DPoP proof-of-possession binding so you don't manually parse Authorization headers or wrestle with python-jose. The skill walks through the automated versus manual Auth0 API setup choice, which is thoughtful since most tutorials skip that decision point. Note it's beta and requires FastAPI 0.115.11 or newer. Common gotcha: you need an Auth0 API resource, not an Application, and the domain goes in as a bare string without the https prefix.
