How can I curl deepcrawl?

My Deepcrawl crawl only give null value.

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL,"https://api.deepcrawl.com/accounts/00000/projects/195334/crawls/1306396/reports/thin_pages_basic");

curl_setopt($ch, CURLOPT_POST, 0);
curl_setopt($ch,CURLOPT_HTTPHEADER,array('X-Auth-Token:Private'));

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output2 = curl_exec ($ch);
curl_close ($ch); 

$results = json_decode($server_output2);

To create a session you first need to manually generate an API Key. This is a key/value pair that can be generated in the API Access page. When you click Generate New API Key, a popup will be displayed with the API Key Value and in the table of Active Keys you can find the API Key ID. This is then sent via Basic Authentication in a POST call to the sessions route.

curl -X POST -u '123:abcdef' https://api.deepcrawl.com/sessions
{
"token":"abcdef123",
"_user_href":"/users/example-user",
...
}

The token returned from the call to sessions is then passed to all API calls as the X-Auth-Token header:

curl -X GET -H 'X-Auth-Token:' https://api.deepcrawl.com/accounts/1/projects

Can someone explain me further about the authentication of deepcrawl? How can I able to curl it using X-Auth-Token only. Sorry for my bad English. Thank you
