Error with when trying to enter information with routes

Question

In api.php have that code:

Route::group(['middleware' => 'api'], function() {
   Route::post('clube/addClube', function(Request $request) {
       return App\clubes::addClube(['name' => $request -> input(['name'])]);
   });
});

In my file I have this method:

methods: {
    addLine(){
       this.list.push({clube: this.clube});
       this.$http.post('api/clube/addClube', this.clube);
    }
}

And in my Modal clubs.php:

namespace App;

use Illuminate\Database\Eloquent\Model;

class BD extends Model
{

}

And returns that error Uncaught TypeError: Cannot read property 'post' of undefined
