title: How to make a JSON call to an URL?
body: <p>I'm looking at the following API:</p>
  <p><a href="http://wiki.github.com/soundcloud/api/oembed-api" rel="nofollow noreferrer">http://wiki.github.com/soundcloud/api/oembed-api</a></p>
  <p>The example they give is</p>
  <p>Call:</p>
  <pre><code>http://soundcloud.com/oembed?url=http%3A//soundcloud.com/forss/flickermood&amp;format=json
  </code></pre>
  <p>Response:</p>
  <pre><code>{
  &quot;html&quot;:&quot;&lt;object height=\&quot;81\&quot; ... &quot;,
  &quot;user&quot;:&quot;Forss&quot;,
  &quot;permalink&quot;:&quot;http:\/\/soundcloud.com\/forss\/flickermood&quot;,
  &quot;title&quot;:&quot;Flickermood&quot;,
  &quot;type&quot;:&quot;rich&quot;,
  &quot;provider_url&quot;:&quot;http:\/\/soundcloud.com&quot;,
  &quot;description&quot;:&quot;From the Soulhack album...&quot;,
  &quot;version&quot;:1.0,
  &quot;user_permalink_url&quot;:&quot;http:\/\/soundcloud.com\/forss&quot;,
  &quot;height&quot;:81,
  &quot;provider_name&quot;:&quot;Soundcloud&quot;,
  &quot;width&quot;:0
  }
  </code></pre>
  <p>What do I have to do to get this JSON object from just an URL?</p>
