No exemplo anterior, as *operações de rota* esperariam um JSON no corpo contendo os atributos de um `Item`, exemplo:

```JSON

    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2

Припустимо, що тепер файл `main.py` із Вашим **FastAPI**-застосунком містить додаткові операції шляху (**path operations**).

Він має `GET`-операцію, яка може повертати помилку.

Він має `POST`-операцію, яка може повертати кілька помилок.

Обидві операції шляху вимагають заголовок `X-Token`.
