TokenMismatchException in VerifyCsrfToken

I am building a REST API and I am getting this error:

TokenMismatchException in VerifyCsrfToken.php line 53:

Here is my routes.php:

Route::controller('city' , 'CityController' );

CityController:

class CityController extends Controller
{  
   public function postLocalities()
  {
    $city = Input::get('cityName');
    $response = $city;
    return $response;
   }
}

Here is the Stacktrace of the error when I hit the URL http://localhost:8000/city/localities?cityName=bangalore with POST method.
