Overview
Auth0 provides auth platform APIs — per-tenant domains (a placeholder tenant returns 404, verified).
Quick Start
Token (replace YOUR_TENANT):
curl -X POST "https://YOUR_TENANT.auth0.com/oauth/token" \
-H "Content-Type: application/json" \
-d '{"grant_type":"client_credentials","client_id":"YOUR_ID","client_secret":"YOUR_SECRET","audience":"https://YOUR_TENANT.auth0.com/api/v2/"}'
Authentication
- Auth0 tenant → client_id + client_secret.
- All endpoints live under your tenant’s domain.
⚠️ Gotcha (verified): a placeholder tenant returns 404 “Unknown host” — use your real tenant.
Rate Limits & Notes
- Free tier with limits (check the docs); paid plans scale.
- Auth/authorization.
FAQ
Is Auth0 free? Free tier with limits; more is paid.
Why 404? The tenant host was a placeholder (verified) — use your tenant.
