Checking a phone number is real after a form submission

Hello :wave: Hope everyone is keeping safe!

A client of mine has a raised a issue, they are paying for paid leads and some of the leads that get filled out by the online form have a fake phone numbers in. So I’ve done some research and come across this website

I spoke to the guys at data-8 they don’t have a integration yet but they said maybe with some custom code following this tutorial could help.

My coding experience is zero, has anyone done anything similar for their clients or could help me out with implementing this to my site

Many Thanks,
