Through comments, we determined the OP would like to alter the results of the user registration service resource...

To alter the results of user registration data, implement hook_services_request_postprocess_alter() in your custom module, for example:

/**
 * Implements hook_services_request_postprocess_alter().
 */
function my_module_services_request_postprocess_alter($controller, $args, &$result) {
  if ($controller['callback'] == '_user_resource_register') {
    $result->foo = 'bar';
  }
}

This will allow the value of foo to be available to your application that is calling the user registration service resource.
