Stack Apps is a question and answer site for apps, scripts, and development with the Stack Exchange API. It's 100% free, no registration required.

I tried to retrieve information of my user profile on Stack Overflow via the API using Ajax/jQuery. But it does not work for me. The result of the request is always empty.

            var req;


            function getReputation(){
                req = new XMLHttpRequest();
                req.open('GET', 'http://api.stackoverflow.com/1.0/users/401025/');
                req.onreadystatechange = processUser;

            function processUser(){
                var res = JSON.parse(req.responseText);

Is that because of the same-domain policy?

However, the Stack Overflow API supports JSONP callbacks, so here is a solution:

function load_script(src) {
    var scrip = document.createElement('script');
    scrip.src = src;
    return scrip;

function soResponse(obj) {

Yes, this is a XSS thing.

You can use JSONP (all API methods take a jsonp parameter for the callback name) to work around this.

Alternatively, you can use one of the Soapi.JS libraries, which handle this for you.

You can also support the feature request to Add CORS headers to API output. (You can read about Cross-origin resource sharing on Wikipedia. –  hippietrail Jun 3 '12 at 13:33
