query Canvas URL using FQL

It seems like http://devel开发者_Go百科opers.facebook.com/docs/reference/fql/application/ provides all the information except for Canvas URL. Is it possible to query this information any other way?

Well, the solution I came up with, was simply calling the old admin.getAppProperties method.

$info = $facebook->api(array(
    'method'        => 'admin.getAppProperties',
    'properties'    => array('publish_url'),
));
