invalid_api_key

API key not recognised · HTTP 401

What causes this

The key is malformed, belongs to another deployment, or has been revoked or rotated. Rotating a key invalidates the previous value immediately.

How to fix it

Check the key under Settings → API keys in the console. If it was rotated, update whatever holds the old value; if revoked, issue a new one.
