javascript

$(function() {
  $.ajax({
    type: "GET",
    url:"https://xmg.minerclaim.net/index.php?page=api&action=public",
    dataType: "json",
    success: function(data) {
      console.log(typeof data); // -- Object
      var json = data;

      $('#balance').html(json.hashrate);

    }
  });
});

As I mentioned above, you are getting bool(true) in your PHP output, because the usage of var_dump() .

An example of a PHP file you could use:

    <?php

        $ch = curl_init();

        curl_setopt($ch, CURLOPT_URL, "https://xmg.minerclaim.net/index.php?page=api&action=public");
        curl_setopt($ch, CURLOPT_HEADER, false);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_POST, 0);

        $headers = array();
        $headers[] = "Content-Type: application/json; charset=utf-8";
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

        $result = curl_exec($ch);
        if (curl_errno($ch)) {
            echo 'Some error:' . curl_error($ch);
            die();
        }

        // You want your browser to think it's JSON, as we return as JSON
        header("Content-Type: application/json; charset=utf-8");
        echo($result);

        curl_close($ch);
?>

You can copy + paste this into a new PHP file, point the $.ajax -url to that new file and see the magic happen. The example above works for me as I'm getting results back.

As for your javascript, you could also try to add contentType: "application/json", after `dataType: "json",", as this will make sure the content-type of the headers that are returned are set.
