API hit using CURL

Question

Am trying to access an API using CURL I can access the API from my browser. But cannot get the data from the same api(using the same API key) using curl.

I am getting this error. 403 Developer Over Qps

Please let me know what can be the reason for this.

Earlier it was working. I am facing this issue for the past 2 days.!!

please check the code below:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://api.perfb.com/api/api.php?requestmethod=json&responsemethod=xml');

curl_setopt($ch, CURLOPT_TIMEOUT, 900);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_FAILONERROR, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $vJson);

$response = curl_exec($ch);
$info = curl_getinfo($ch);
echo '<pre>';
print_r($info);exit;

Answer 1

Qps means Queries Per Second

Are you hitting the server repeatedly with curl in a loop for example? Try adding a pause after each call and see if that works.

Answer 2

That error usually signifies that you're hitting the server too often (ie developer over allowed queries per second). Slow down your code, put some delays in. In browser, you're doing it manually, so it's likely quite a bit slower than your code.
