=item * B<in> => I<any>

Return value:

Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error).

Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.
