Üstelik, sadece aynı Python tip tanımlaması ile, **FastAPI** size otomatik ve interaktif (Swagger UI ile entegre) bir dokümantasyon sağlar.

Тепер коли відкриєте свій браузер за посиланням <a href="http://127.0.0.1:8000/docs" class="external-link" target="_blank">http://127.0.0.1:8000/docs</a>, то побачите автоматично згенеровану, інтерактивну API-документацію:

/// check | Примітка

Знову ж таки, лише з цим самим оголошенням типу в Python, FastAPI надає вам автоматичну, інтерактивну документацію (з інтеграцією Swagger UI).

You'll see the user interface like:

Authorize the application the same way as before.

Using the credentials:

Username: `johndoe`
Password: `secret`

Notice that nowhere in the code is the plaintext password "`secret`", we only have the hashed version.

* Run the debugger with the option "`Python: Current File (Integrated Terminal)`".

It will then start the server with your **FastAPI** code, stop at your breakpoints, etc.

Here's how it might look:
