Sehingga **FastAPI** menyediakan dokumentasi alternatif (menggunakan ReDoc), yang bisa diakses di <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>:

**Typer** є молодшим братом FastAPI. І це **FastAPI для CLI**. ⌨️ 🚀

## Вимоги

FastAPI стоїть на плечах гігантів:

* <a href="https://www.starlette.io/" class="external-link" target="_blank">Starlette</a> для web частини.
* <a href="https://docs.pydantic.dev/" class="external-link" target="_blank">Pydantic</a> для частини даних.

The process that happens when your API app calls the *external API* is named a "callback". Because the software that the external developer wrote sends a request to your API and then your API *calls back*, sending a request to an *external API* (that was probably created by the same developer).

* <a href="https://x.com/tiangolo" class="external-link" target="_blank">Śledzić mnie na **X (Twitter)**</a> lub na <a href="https://fosstodon.org/@tiangolo" class="external-link" target="_blank">Mastodonie</a>.
    * Napisz mi, w jaki sposób korzystasz z FastAPI (uwielbiam o tym czytać).
    * Dowiedz się, gdy ogłoszę coś nowego lub wypuszczę nowe narzędzia.

Because of this, **FastAPI** itself provides an alternative API documentation (using ReDoc), which you can access at <a href="http://127.0.0.1:8000/redoc" class="external-link" target="_blank">http://127.0.0.1:8000/redoc</a>:

<img src="/img/tutorial/path-params/image02.png">

* <a href="https://x.com/tiangolo" class="external-link" target="_blank">Seguirme en **X (Twitter)**</a> o <a href="https://fosstodon.org/@tiangolo" class="external-link" target="_blank">Mastodon</a>.
    * Contarme cómo usas FastAPI (me encanta oír eso).
    * Enterarte cuando hago anuncios o lanzo nuevas herramientas.
