The API is at https://www.ipify.org/

The API endpoint is https://api.ipify.org?format=json

function httpGetAsync(theUrl, callback)
{
    var xmlHttp = new XMLHttpRequest();
    xmlHttp.onreadystatechange = function() { 
        if (xmlHttp.readyState == 4 && xmlHttp.status == 200)
            callback(xmlHttp.responseText);
    }
    xmlHttp.open("GET", theUrl, true); // true for asynchronous 
    xmlHttp.send(null);
}

function callbackHandler(data){
  console.log(data)
}

httpGetAsync('https://api.ipify.org?format=json', callbackHandler)
