```JSON
{
  "item": "The Foo Wrestlers"
}
```

Але якщо клієнт робить запит на `http://example.com/items/bar` (де `item_id` має не існуюче значення `"bar"`), то отримає статус-код 404 (помилка "не знайдено") та відповідь:

```JSON
{
  "detail": "Item not found"
}
```

이를 위해 `jsonable_encoder` 를 사용할 수 있습니다.

Pydantic 모델과 같은 객체를 받고 JSON 호환 가능한 버전으로 반환합니다:

{* ../../docs_src/encoder/tutorial001.py hl[5,22] *}

이 예시는 Pydantic 모델을 `dict`로, `datetime` 형식을 `str`로 변환합니다.

이렇게 호출한 결과는 파이썬 표준인 <a href="https://docs.python.org/3/library/json.html#json.dumps" class="external-link" target="_blank">`json.dumps()`</a>로 인코딩 할 수 있습니다.
