Get data (json format) from another domain without jsonp

How can i get data (json format) from another domain?
My problem is: I want to get data from: http://pin-codes.in/api/pincode/400001/
I have tried to use CORS but it didn't work.
My console is:
GET http://pin-codes.in/api/pincode/400001 [HTTP/1.1 200 OK 780ms]
Error Error
My code by client-script:

$(document).ready(function() {
 $("#get_data_btn").click(function() {
   var data_path = "http://pin-codes.in/api/pincode/400001";
   $.getJSON(data_path, null)
    .done(function(data) {
      console.log("Success: " + data.status);
    })
    .fail(function(jqxhr, textStatus, error) {
      console.log("Error Error");
    });
 });
});

You probably don't own the other domain right?

No problem at all. Never mind nay-sayers, in computing everything is a yay!

Just use a simple proxy on your server or look into YQL.

this simple query will work: 

select * from json where url="http://pin-codes.in/api/pincode/400001/ "

Just test this link (bypassing cross-domain security bull$#!7).
It will get the data you requested as normal plain json (no jsonp) data wrapped in callback-function cbfunc.

Have a look at this question for further info (I did quite a lot of yql scrape answers on SO).

Update:

Here is a crude fiddle demonstrating the whole process: so you enter a url, click fetch and watch the magic happen: http://jsfiddle.net/NbLYE/

function getJSON(url) {  //quick and dirty
  var script = document.createElement('script');
  script.setAttribute('src', url);
  script.setAttribute('type', 'text/javascript');
  document.getElementsByTagName('head')[0].appendChild(script);
}

function cbfunc(json){     //the callback function
   if(json.query.count){ 
      var data=json.query.results.json;
      // do your work here, like for example:
      //document.getElementById('output').innerHTML=data.toSource();
   } else {
      alert('Error: nothing found'); return false;
   }
}

function fetch(url){         //scrape the url you'd want
   var yql="select * " + 
           " from json" +
           " where url='" + url + "';";
   yql="http://query.yahooapis.com/v1/public/yql?q=" +
       encodeURIComponent(yql) +
       "&format=json" +
       "&callback=cbfunc";
   getJSON(yql);
}

That should get you started (and motivated that it is easy).

Hope this helps!

You can't do it using jquery only, you can use any server side script like PHP

Try using php,

<?php
    echo file_get_contents('http://pin-codes.in/api/pincode/400001');
?>

Save above code in pincode.php and use jquery like,

$(document).ready(function() {
    $("#get_data_btn").click(function() {
        var data_path = "pincode.php";
        $.getJSON(data_path, null)
            .done(function(data) {
                console.log("Success: " + data.status);
            })
            .fail(function(jqxhr, textStatus, error) {
                console.log("Error Error");
            });
    });
});

You don't have the correct CORS headers on your server.

You need to add

Access-Control-Allow-Origin: *

(or something similar) server-side to the response.

Edit: From the HTTP response, it appears you are using PHP. Use the header function in your response.

<?php header('Access-Control-Allow-Origin: *'); ?>
