পূর্ববর্তী কোড উদাহরণে ফিরে আসা যাক, **FastAPI** যা করবে:

- `GET` এবং `PUT` অনুরোধের জন্য পথে `item_id` আছে কিনা তা যাচাই করবে।
- `GET` এবং `PUT` অনুরোধের জন্য `item_id` টাইপ `int` এর হতে হবে তা যাচাই করবে।
  - যদি না হয় তবে ক্লায়েন্ট একটি উপযুক্ত, পরিষ্কার ত্রুটি দেখতে পাবেন।

    * Swagger UI.
    * ReDoc.

Visszatérve az előző kód példához. A **FastAPI**:

* Validálja hogy van egy `item_id` mező a `GET` és `PUT` kérésekben.
* Validálja hogy az `item_id` `int` típusú a `GET` és `PUT` kérésekben.
    * Ha nem akkor látni fogunk egy tiszta hibát ezzel kapcsolatban.
