Here we are using `Query()` because this is a **query parameter**. Later we will see others like `Path()`, `Body()`, `Header()`, and `Cookie()`, that also accept the same arguments as `Query()`.

///

FastAPI will now:

* **Validate** the data making sure that the max length is 50 characters
* Show a **clear error** for the client when the data is not valid

Sadece bu Python type tanımıyla, **FastAPI** şunları yapar:

* Request'in body'sini JSON olarak okur.
* İlgili type'lara dönüştürür (gerekirse).
* Veriyi doğrular (validate eder).
    * Veri geçersizse, tam olarak nerede ve hangi verinin hatalı olduğunu söyleyen, anlaşılır bir hata döndürür.
* Aldığı veriyi `item` parametresi içinde size verir.
