Next open controller, Go to app/HTTP/Controller/CurrencyController and put the below code here :

use Guzzle\Http\Exception\ClientErrorResponseException;
use carbon\Carbon;
class CurrencyController extends Controller
{
//
public function index() {
return view('currency');
}
public function exchangeCurrency(Request $request) {
$amount = ($request->amount)?($request->amount):(1);
$apikey = 'd1ded944220ca6b0c442';
$from_Currency = urlencode($request->from_currency);
$to_Currency = urlencode($request->to_currency);
$query = "{$from_Currency}_{$to_Currency}";
// change to the free URL if you're using the free version
$json = file_get_contents("http://free.currencyconverterapi.com/api/v5/convert?q={$query}&compact=y&apiKey={$apikey}");
$obj = json_decode($json, true);

$total = $val['val'] * 1;
$formatValue = number_format($total, 2, '.', '');
$data = "$amount $from_Currency = $to_Currency $formatValue";
echo $data; die;
