Question

Why can’t I get this JSON when it’s properly formatted?

jQuery.getJSON("http://sandbox.buscape.com/service/findProductList/564771466d477a4458664d3d/?keyword=drive&format=json", function(result){

        alert('ok');

    });

Because it comes from a different domain. You have to use JSONP, luckily the API you are using supports it (by setting the callback parameter):

$.ajax({
    dataType : 'jsonp',
    url : 'http://sandbox.buscape.com/service/findProductList/564771466d477a4458664d3d/?keyword=drive&format=json&callback=?',
    success : function(data) {
        console.log(data);
    }
});
