## Other responses

- `400`: A query parameter is malformed or outside its allowed values. `error.details` names the parameter.
- `401`: The credential is missing, invalid, expired or revoked (`unauthorized`), or was sent in a way v3 doesn't accept (see the examples).
- `403`: The credential isn't allowed to do this. `error.code` says why. An account or project the credential doesn't cover is 404 `not_found`, not 403.
- `404`: Resource not found
- `422`: No path names the account, so the API token has to. This is returned when the token covers more than one account and the account a request applies to cannot be determined. Use a token bound to a single account.
