Status 401
invalid_key
The API key is not valid
Why it happens
The key in Authorization: Bearer is not valid, was regenerated, or its account has no active plan. The API never falls back to the free tier for a call that meant to use a key.
What to do
Copy the current key from the API section of your Account settings, and check that the plan is active. Regenerating a key ends the old one at once.
