클라이언트가 **추가 헤더**를 보내려고 시도하면, **오류** 응답을 받게 됩니다.

예를 들어, 클라이언트가 `plumbus` 값으로 `tool` 헤더를 보내려고 하면, 클라이언트는 헤더 매개변수 `tool`이 허용 되지 않는다는 **오류** 응답을 받게 됩니다:

```json
{
    "detail": [
        {
            "type": "extra_forbidden",
            "loc": ["header", "tool"],
            "msg": "Extra inputs are not permitted",
            "input": "plumbus",
        }
    ]
}
```

Por ejemplo, si el cliente intenta enviar un header `tool` con un valor de `plumbus`, recibirán un response de **error** indicando que el parámetro de header `tool` no está permitido:
