[web2py] Using The Google Translator

[Rahul]

Hey All,
         I am really confused - I want to know if I need to pay for using 
the below code into my webpage ? This invokes the google translator online.

    <div id="google_translate_element"></div><script>
        function googleTranslateElementInit() {
        new google.translate.TranslateElement({
        pageLanguage: 'en'
        }, 'google_translate_element');
        }
    </script><script 
src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>
    
Cheers Rahul D
