Az önceki örneğe geri dönelim, **FastAPI**'ın yapacaklarına bir bakış atalım:

* `item_id`'nin `GET` ve `PUT` istekleri için, yolda olup olmadığının kontol edecek.
* `item_id`'nin `GET` ve `PUT` istekleri için, tipinin `int` olduğunu doğrulayacak.
    * Eğer değilse, sebebini belirten bir hata mesajı gösterecek.

class Item(BaseModel):
    name: str
    description: Union[str, None] = None
    price: float
    tax: Union[float, None] = None

    images: Union[List[Image], None] = None


@app.put("/items/{item_id}")
async def update_item(item_id: int, item: Item):
    results = {"item_id": item_id, "item": item}

Возвращаясь к предыдущему примеру кода, **FastAPI** будет:

* Проверять наличие `item_id` в пути для запросов `GET` и `PUT`.
* Проверять, что `item_id` имеет тип `int` для запросов `GET` и `PUT`.
    * Если это не так, клиент увидит полезную чёткую ошибку.
