Answer 1

You're probably trying to access a file that needs you to have api accesses. If you haven't signed up with them, then you don't have access. If you just want to see the docs, here they are.
EDIT: btw, you need to request an API Key per their docs, and you can't even view their docs until you've signed up for an account. Once you do that, they will personally approve or deny you access to keys. With that, you have about one month to do something with it.

If you have secure token use this code:
For Json response:
Method defines GET or POST,
headers contains header part,
url is rightsignature endpoints,
secure token got after registration,
Body contains parameters.
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
// Append 'api-token' to Headers
curl_setopt($curl, CURLOPT_HTTPHEADER, array($headers, "api-token: $secure_token")); // Set the headers.
// If you want parameters to be sent
if ($body) {
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $body);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);
// Append 'api-token' to Headers
curl_setopt($curl, CURLOPT_HTTPHEADER, array($headers, "Content-Type: application/javascript;charset=utf-8", "api-token: $secure_token"));
}
For XML response:
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
// Append 'api-token' to Headers
curl_setopt($curl, CURLOPT_HTTPHEADER, array($headers, "api-token: $secure_token")); // Set the headers.
// If you want parameters to be sent
if ($body) {
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $body);
curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $method);
// Append 'api-token' to Headers
curl_setopt($curl, CURLOPT_HTTPHEADER, array($headers, "Content-Type: text/xml;charset=utf-8", "api-token: $secure_token"));
}
