* Pól tekstowych (`str`) z określeniem minimalnej i maksymalnej długości.
    * Liczb (`int`, `float`) z wartościami minimalnymi, maksymalnymi, itp.

* Walidacja bardziej egzotycznych typów danych, takich jak:
    * URL.
    * Email.
    * UUID.
    * ...i inne.

Cała walidacja jest obsługiwana przez ugruntowaną i solidną bibliotekę **Pydantic**.
