How to check if a phone number is using authy [Tutorial] - Larry. - Aug 26, 2017

It's pretty simple.

https://api.authy.com/json/users/countrycode-phonenumber/status

you get information about the userid of the phone number and how many devices connected to his authy.

free node.js script :P
Code
const request = require("request");

request.get("https://api.authy.com/json/users/countrycode-phone/status", function(err,res,body) {
  console.log(body);
})
