There is no such function to retrieve the URL in your way. You need to do it manually. Create a helper called base_helper.php inside helpers directory and write this code.

if (!defined('BASEPATH'))
    exit('No direct script access allowed');

if (!function_exists('url')) {

    function url($param = TRUE)
    {
        if ($param) {
            return 'http://site.com/';
        }
        return 'http://api.site.com/';
    }

}

You can call this helpers in controllers/views you wish. Use true and false parameter to get main domain or sub domain.

$this->load->helper('base');
echo url();
echo "
";
echo url(false);

Prints

http://site.com/
http://api.site.com/

Hope this helps you. Thanks!!
