Auth0 Integration

Auth0 for enterprise SSO, the kit's API keys for programmatic access.

Auth0 is a strong fit when you need enterprise SSO, SAML, or complex identity federation for human users. FastAPI AI Kit's JWT/API-key layer stays focused on what it's built for: authenticating and rate-limiting programmatic API calls.

Setup in 4 steps

1Validate incoming Auth0-issued JWTs at your edge or gateway layer if you need SSO for human dashboard access
2Issue a separate kit API key for programmatic/service access, mapped to the Auth0 user or org ID
3Use the kit's existing rate limiting and Stripe metering against the issued API key, not the Auth0 token directly
4Keep Auth0 tenant/org IDs in your Postgres schema for per-organization reporting

What's included

Enterprise SSO/SAML requirements handled by Auth0, not reimplemented in FastAPI
Kit's rate limiting and billing continue to operate on its own API key format
Clean separation of concerns: identity provider vs API authorization layer
Useful when a customer's IT requirements demand a specific SSO provider you don't control

Code example

example.py

# Validate Auth0 JWT for dashboard/admin routes only
from jose import jwt

async def verify_auth0_token(token: str):
    return jwt.decode(token, AUTH0_PUBLIC_KEY, audience=AUTH0_AUDIENCE)

# Programmatic API routes keep using the kit's own API keys
@router.post("/v1/chat")
@require_api_key(tier=["basic", "pro"])
async def chat(...): ...
