I suggest using Dancer::Plugin::REST for using status_ERROR, like:

     if ($missing_parameter) {
         return status_bad_request("Missing parameter $foo");
     }

Or manually, the send_entity() method:

     if ($missing_parameter) {
         return send_entity({ error => "Missing parameter $foo"}, 400);
     }

This how we handle this case at work with our Dancer-powered API webservice.

for details
