 You can write a JavaScript handler to process the callback. Here's a minimal example you can try out:
 
-<pre><code class="language-html">&lt;html>
-&lt;head>
-&lt;script type="text/javascript">
-function foo(response) {
-  var meta = response.meta
-  var data = response.data
-  console.log(meta)
-  console.log(data)

-
-var script = document.createElement('script');
-script.src = 'https://api.github.com?callback=foo'
-
-document.getElementsByTagName('head')[0].appendChild(script);

-&lt;/head>
-
-&lt;body>
-&lt;p>Open up your browser's console.&lt;/p>
-&lt;/body>

 All of the headers are the same String value as the HTTP Headers with one
 notable exception: Link.  Link headers are pre-parsed for you and come
