Por ejemplo, si el cliente intenta enviar un parámetro query `tool` con un valor de `plumbus`, como:

```http
https://example.com/items/?limit=10&tool=plumbus
```

Recibirán un response de **error** que les indica que el parámetro query `tool` no está permitido:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",

        }
        if (elements.length > 1) {
          /*
           * When a test requests a multiset with duplicates, our plan of
           * "add an extra item 0 to A and an extra item 1 to B" really means
           * "add an extra item 0 to A and B," which isn't what we want.
           */
          if (!Objects.equals(elements[0], elements[1])) {
            multiset2.add(elements[1], 2);
          }
        }

`response_model` receives the same type you would declare for a Pydantic model field, so, it can be a Pydantic model, but it can also be, e.g. a `list` of Pydantic models, like `List[Item]`.

FastAPI will use this `response_model` to do all the data documentation, validation, etc. and also to **convert and filter the output data** to its type declaration.

#### Dados com os mesmos valores que os padrões

Se os dados tiverem os mesmos valores que os padrões, como o item com ID `baz`:

```Python hl_lines="3 5-6"

For example, if the client tries to send a `tool` query parameter with a value of `plumbus`, like:

```http
https://example.com/items/?limit=10&tool=plumbus
```

They will receive an **error** response telling them that the query parameter `tool` is not allowed:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
