I signed up a paid app at Mashape, my plan is to use it on my website, allow users upload and delete imgur images (anonymously).
I am just confusing is there any UserLimit for paid app, because my app will be only called by my server IP.
Another question is that how to check rate limit? I use the following code that always return blank page to me. ( IMGUR_CLIENT_ID and IMGUR_MASHAPE_KEY are already defined correctly)
$curl = curl_init();
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
'Authorization: Client-ID ' . IMGUR_CLIENT_ID,
'X-Mashape-Key: ' . IMGUR_MASHAPE_KEY
));
$url = '
https://imgur-apiv3.p.mashape.com/3/credits';
curl_setopt($curl,CURLOPT_URL, $url);
curl_setopt($curl,CURLOPT_RETURNTRANSFER,true);
$output = curl_exec($curl);
curl_close($curl);
return $output; // $output is null
