Google Translate javascript API

[Minoru]

I am trying to incorporate Google Translate javascript API into my application.

I understand that a usage fee is charged for Google Cloud Translation.

I was just wondering if I could use the following javascript free of charge:

<script type="text/javascript"> src="//translate.google.com/translate_a/element.js?cb=googleTranslateElementInit"></script>

Is it OK to apply this script to commercial use free of charge?

Or is it also covered under the Google Cloud Translation policy?

KInd regards,
