title: Facebook JSON API for 'Linting' URL
body: <p>The <a href="https://developers.facebook.com/tools/debug/og/object/" rel="nofollow">Facebook Open Graph Debugger</a> does a terrific job of taking a URL and parsing / loading it into a title / description / image / etc. Does this API expose a JSON format or does a similar service exist for 'linting' URLs into more rich objects? I'm trying to do an iOS integration. Obviously I'd like to avoid parsing XML and extracting the metadata myself if possible.</p>
