Curl парсер валют

Почему выдает stdClass Object ( [statusCode] => 404 [error] => Not Found [message] => Cannot POST /api/quotesTick?m=json&q=USDRUR,EURRUR,gold,silver ) , хотя если в браузер вставить то выдает курсы

<?php
$tpl = $modx->getOption('tpl',$scriptProperties,'tpl.currency');
$url = ('https://quotes.instaforex.com/api/quotesTick?m=json&q=USDRUR,EURRUR,gold,silver');
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json"));
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $json);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$result = curl_exec($ch);
$obj = json_decode($result);
//print_r($obj);
curl_close($ch);
$output = '';
//echo $obj->ask;
foreach($obj as $row){
    $output .= "
        <tr>
            <td>".$row->symbol."</td>
            <td>".$row->ask."</td>
            <td>".$row->bid."</td>
            <td>".$row->change."</td>
            <td>".$row->position->sell."</td>
            <td>".$row->position->buy."</td>
            <td>".$row->minmax->min."</td>
            <td>".$row->minmax->max."</td>
        </tr>
    ";
    //echo $row->ask;
}
//print($result);
return $output;
