Struggling with Bing's json request (bing search, not map), I am getting an error back that says 'Invalid Label'

My query url is:

var bingurl="http://api.search.live.net/json.aspx?Appid=##APIKEY##&query=Honda&sources=web";


 $.ajax({
            type: "GET",
            url: bingurl,
            data: "{}",
            contentType: "application/json; charset=utf-8",
            dataType: "jsonp",
            success: function(data) {

                $callBack(data);
            },
            error: function(msg) {
                alert("error" + msg);
            }
        });

Firebug reports 'invalid label' and then dumps the json response.

No idea what is wrong? help appreciated.
