How to send JSON received as a result of the js script to the user's request?

Question

JavaScript

I am developing an app for Pebble. Two addresses are passed as parameters, and at any time from the clock you can see the travel time, taking into account traffic jams. Pebble can receive information in the following way:

var cityName = 'London';
var URL = 'http://api.openweathermap.org/data/2.5/weather?q=' + cityName;

ajax(
 {
  url: URL,
  type: 'json'
},
function(data) {
  // Success!
  console.log('Successfully fetched weather data!');
},
function(error) {
  // Failure!
  console.log('Failed fetching weather data: ' + error);
}
);

I wrote a small script:

var route;
      ymaps.ready(init);
var myMap;

function init(){    


  function getParameterByName(name) {
    name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]");
    var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"),
        results = regex.exec(location.search);
    return results === null ? "" : decodeURIComponent(results[1].replace(/\+/g, " "));
  }   

        var time = 0;
        var home = getParameterByName("h");
        var work = getParameterByName("w");
      ymaps.route([home, work],{avoidTrafficJams: true}).then(
            function (router) {
                route=router;
                time = ((route.getTime())/60).toFixed(2);

               var info = new Object;
                info["home"] = home;
                info["work"] = work;
                info["time"] = ~~time+"m"+~~((time%1)*60)+"s";
                JSON.stringify(info);
            },
            function (error) {
                alert('Возникла ошибка: ' + error.message);
            }
            );    
}

It turns out that I have a JSON string that I generate on the go, but I can't figure out how to properly send it to clients.
Perhaps I fundamentally misunderstand something, I'm not very good at programming. Thank you in advance!

<?
header("Content-Type: text/plain");
echo json_encode($output);
