if (curl_errno($ch)) {
print "Error: " . curl_error($ch);

You do not use correctly CURLOPT_HTTPHEADER. From the manual:

http://php.net/manual/en/function.curl-setopt.php

CURLOPT_HTTPHEADER An array of HTTP header fields to set, in the format array('Content-type: text/plain', 'Content-length: 100')

So you would need:

  curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'X-Sifter-Token: 343b1b831066a40e308e0af92e0f06f0',
        'Accept: application/json',
  ));
