I need to get an info about the app/song/video by item id from iTunes Store.

I\'ve found this

But it doesn\'t work with apps.

Is there any public API

I wrote this script for myself. It's not optimized or future-proof, but it's working for me in the meantime...

Four stars: " . $ratings[1];
    echo "
Three stars: " . $ratings[2];
    echo "
Two stars: " . $ratings[3];
    echo "
One star: " . $ratings[4];

    echo "
Total ratings: " . getTotalRatings($ratings);

    echo "
Average rating: " . getAverageRating($ratings);
}

function getTotalRatings($ratings)
{
    $temp = 1;

    for($i=0; $i < count($ratings); ++$i) 
        $temp+=$ratings[$i];

    return $temp;
}

function getAverageRating($ratings)
{
    $totalRatings = getTotalRatings($ratings);
    return round(5*($ratings[0]/$totalRatings) 
                                + 4*($ratings[1]/$totalRatings) 
                                    + 3*($ratings[2]/$totalRatings)
                                        + 2*($ratings[3]/$totalRatings) 
                                            + 1*($ratings[4]/$totalRatings),2);
}

function getXML($ratings)
{   
    header('Content-type: text/xml');
    header('Pragma: public');        
    header('Cache-control: private');
    header('Expires: -1');
    echo '';
    echo '';
    echo ''.$ratings[0].'';
    echo ''.$ratings[1].'';
    echo ''.$ratings[2].'';
    echo ''.$ratings[3].'';
    echo ''.$ratings[4].'';
    echo ''.getTotalRatings($ratings).'';
    echo ''.getAverageRating($ratings).'';
    echo '';
}

?>
