        Optional. An identifier for the user profile (workspace) making the
        request. This is no longer required as the API key already includes your
        workspace information. If provided, it helps in associating the lookup
        with a specific user, allowing for data retrieval and credit tracking. 

         Check out `user details` endpoints under the Profile tab for more information.
