using this as a guide: http://msdn.microsoft.com/en-us/library/dd250846.aspx

can someone help me with the jquery call?

Do I actually pass in the javascript code for the callback, or just the name of the function?

BingSearch = function($bingUrl, $bingAppID, $keyword, $callBack) {

        $bingUrl = $bingUrl + "?JsonType=callback&JsonCallback=" + $callBack + "&Appid=" +                  $bingAppID + "&query=" + encodeURI($keyword) + "&sources=web";


$.ajax({
            dataType: 'jsonp',
            jsonp: $callBack,
            url: $bingUrl,
            success: function(data) {
                alert('success');
                $callBack(data);
            },
            error: function(XMLHttpRequest, textStatus, errorThrown) {
                alert("error: " + textStatus);
            }
        });

};
