Retrieving the full instrument list

I need to retrieve the instrument list api. I have the access token, but I am getting response as method not found. I only subscribed to Kite Connect subscription. I have not subscribed to historical data subscription.

$request_headers = ["Content-type: application/x-www-form-urlencoded",
"Accept-Encoding: gzip, deflate",
"Accept-Charset: UTF-8,*;q=0.5",
"X-Kite-Version: 3",
"Authorization: token api_key: xxx",

];

// $params = [

// "api_key" => 'R044DOKIoLMNGFgM7OnuhYIGJLxEMg4a',

// ];
// $request_headers[] = "Authorization: token " . $this->api_key . ":" . $this->access_token;


$resp = curlexec('https://api.kite.trade/instruments/historical/5633/minute?from=2015-12-28+09:30:00&to=2016-01-01+10:30:00', 'POST', $request_headers, $params);
print_r($resp);


I am getting the following response.
