How to use REST with MVC when there is no Database?

I have two servers, the first works using REST and other Webs pages that are built using MVC.

I usually always run REST commands in the Controller layer, however I am with a doubt, assuming that my project (using MVC) does not use database and I'm using Controllers only to send commands to the webservice to send and receive information.

• The REST in this case would be equivalent to Model?

  In this case I should call the Rest within the Controllers and not create Models. eg .:

  public function createProductAction() {
      $rest = Rest('ws.example.com', 'PUT /items/', array(
                                          'price' => $price,
                                          'description' => $descricao
                                      ));
  
      if ($response->status === 200) {
          View::show('success.tpl');
      } else {
          View::show('error.tpl', $rest->error);
      }
  }
  
  

or

• I would have to create Models to make the calls to REST?

  For example:

  class ProductsModel
  {
      public function putItem($preco, $descricao)
      {
          $rest = Rest('ws.example.com', 'PUT /items/', array(
                                              'price' => $price,
                                              'description' => $descricao
                                          ));
  
          //If status=200 new product is added
          return $response->status === 200;
      }
  
      public function deleteItem($id)
      {
          Rest('ws.example.com', 'DELETE /items/{id}', array(
                                              'id' => $id
                                          ));
  
          $response = json_decode($rest->getRespose());
  
          //If status=200 product is deleted
          return $response->status === 200;
      }
  
      public function getItem($id)
      {
          $rest = Rest('ws.example.com', 'GET /items/{id}', array(
                                              'id' => $id
                                          ));
  
          $response = json_decode($rest->getRespose());
          if ($response->status === 200) {
              //If status=200 return data
              return $response->data;
          }
  
          return NULL;
      }
  }
  
  

How should I proceed?
