# unauthenticated

Authentication required: HTTP 401.

HTTP 401 · Authentication required

## Meaning
The credential is missing where one is required, or the key or token sent is unknown, revoked or expired.

## Fix
Send a valid key in the Authorization header. A key that worked before may have been rotated or revoked: check it in your account.

## Retry
The same call fails again until something changes.
