That’s because your “mount” for the api.pm routes prepends ‘/api’ to them.  When you use the module standalone as you’re attempting to now, that bit is stripped off.  You’ll find that you now have /userdata/$stuff now.

Easy fix: wrap the route definitions in api.pm in a prefix block:

    prefix '/api' => sub {
        any ['get', 'post'] => '/userdata/:user' => sub {
            # etc
        };
    };

You could even extract the other layer, too:

    prefix '/api' => sub {
        prefix '/userdata' => sub {
            any ['get', 'post'] => ':user' => sub {
                # etc
            };
        };
    };
