Domain Tokens

To avoid exposing your API key in browser code, Domain Tokens can used in place of your API key.
Domain Tokens can be generated for a specific domain and it's sub-domains. They can also limit the number of look-ups per minute for an IP address. 

<script>
    getAddress.autocomplete
    (
        'textbox_id',
        'dtoken_hEDzcyiWMI1eXXXX'
    );
</script>
