PSGI and WSDL - How "public" that WSDL?

Question

My problem is that I have these two files:

1.- marcas.psgi

#!/usr/bin/perl

use strict;
use warnings;

use WWW::Curl::easy;
use WWW::Curl;

use Data::Dumper qw(Dumper);
$Data::Dumper::Sortkeys = 1;

use Plack::Request;

my $app = sub {

    ### Pasandole los valores desde el $env
    my $env = shift;
    my $request = Plack::Request->new($env);

    my $MARCA1 = "";
    my $MARCA2 = "";
    my $MARCA3 = "";
    my $MARCA4 = "";
    my $MARCA5 = "";

    if ($request->param('MARCA1')) {
        $MARCA1 = $request->param('MARCA1');
    }
    if ($request->param('MARCA2')) {
        $MARCA2 = $request->param('MARCA2');
    }
    if ($request->param('MARCA3')) {
        $MARCA3 = $request->param('MARCA3');
    }
    if ($request->param('MARCA4')) {
        $MARCA4 = $request->param('MARCA4');
    }
    if ($request->param('MARCA5')) {
        $MARCA5 = $request->param('MARCA5');
    }

    #print system('php','-r','echo "Hola\n";');
    my $resultado = `php -r '
            include_once "marcas.php";
            prueba_curl("$MARCA1","$MARCA2","$MARCA3");
        '
    `;
    #print $resultado;

    return [
        '200',
        [ 'Content-Type' => 'text/plain' ],
        [ "<h1>".time()."</h1><br><br>".
          "MARCA1: ".$MARCA1."<br>".
          "MARCA2: ".$MARCA2."<br>".
          "MARCA3: ".$MARCA3."<br><hr><br>".
          $resultado."<br><hr><br>" ],
    ];

}

To run the marcas.psgi what I do is:

plackup marcas.psgi

How I can do to access that marcas.psgi through the WSDL? How "public" that WSDL?

Thank you very much for everything.
