Щоб побачити всі доступні варіанти, ознайомтеся з оглядом <a href="https://docs.pydantic.dev/latest/concepts/types/" class="external-link" target="_blank">типів у Pydantic</a>. Деякі приклади будуть у наступних розділах.

Наприклад, у моделі `Image` є поле `url`, тому ми можемо оголосити його як `HttpUrl` від Pydantic замість `str`:

/// info | Información

`Query`, `Path` y otras clases que verás más adelante son subclases de una clase común `Param`.

Todas ellas comparten los mismos parámetros para validación adicional y metadatos que has visto.

///

/// note | Nota técnica

Cuando importas `Query`, `Path` y otros de `fastapi`, en realidad son funciones.

Que cuando se llaman, retornan instances de clases con el mismo nombre.
