Please use like that:-

<?php

class process extends CI_Controller {

    function curlAPI(){
        $headers = 'Content-Type:application/json';
        $process = curl_init('https://jsonplaceholder.typicode.com/users'); //your API url
        curl_setopt($process, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($process, CURLOPT_HEADER, 1);
        curl_setopt($process, CURLOPT_TIMEOUT, 20);
        curl_setopt($process, CURLOPT_POST, 1);

        curl_setopt($process, CURLOPT_RETURNTRANSFER, TRUE);
        $return = curl_exec($process);
        curl_close($process);
        print_r($return);
    }
}

?>
