Curl not returning any results

I don't really understand how curl works and this is my first time using curl in laravel. Whenever i try to make a call to any url i get noting, no errors, just no results. here is the code....tell me what you think the error is

THE ROUTE
// HACK: CURL call
Route::get('/ajaxa', [
'uses' => '\Skylearn\Http\controllers\CurlController@curl',
       'as'  => 'ajaxa.index',
       'middleware' => ['auth'],
]);

THE CONTROLLER

class CurlController extends controller
  {
    public function curl()
    {
 $response = Curl::to('https://curl-url')
        ->get();
       
    }


// REVIEW:// DO NOT REMOVE THE CLOSING TAGS BELOW
  }

THE BLADE AS JUST HELLO WORLD I DON'T KNOW IF I SHOULD MAKE A CALL OR NOT

<p>hello world</p>

I really need curl in this project and i would love it if anyone can answer this... Thanks a lot.
