// set endpoint and your access key
var access_key = 'YOUR_ACCESS_KEY';
var email_address = '[email protected]';
var catch_all = 1;

// verify email address via AJAX call
url: 'http://apilayer.net/api/check?access_key=' + access_key + '&email=' + email_address + '&catch_all=' catch_all,
dataType: 'jsonp',
success: function(json) {
