Hi, We are trying to show the number of files in a Commons category[1] at a page in meta[2],  but we are not sure how to make interwiki calls as most browsers block it.

You can use JSONP with a URL like http://commons.wikimedia.org/w/api.php?action=query&whatever=youneed&... . Or in jQuery AJAX that would be:

$.getJSON( 'http://commons.wikimedia.org/w/api.php?callback=?', {'action': 'query', 'whatever': 'youneed', 'format': 'json' }, function( data ) { .... } );

jQuery automatically replaces the ? in callback=? with a randomly generated function name and makes sure your callback is called.
