 * The HTTP `401 Unauthorized` client error status response code indicates that the request has not been applied because it lacks valid authentication credentials for the target resource.

 * This status is sent with a [WWW-Authenticate](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/WWW-Authenticate) header that contains information on how to authorize correctly.
 *
 * This status is similar to [403](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/403), but in this case, authentication is possible.
 *
 * @see [401 Unauthorized](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/401)
 * @param options - These are the same types as ApiResponse
