By default, **FastAPI** will return the responses using a `JSONResponse`, putting the content you return from your *path operation* inside of that `JSONResponse`.

It will use the default status code or the one you set in your *path operation*.

Ein „Pfad“ wird häufig auch als „Endpunkt“ oder „Route“ bezeichnet.

///

Bei der Erstellung einer API ist der „Pfad“ die wichtigste Möglichkeit zur Trennung von „Anliegen“ und „Ressourcen“.

#### Operation

„Operation“ bezieht sich hier auf eine der HTTP-„Methoden“.

Eine von diesen:

* `POST`
* `GET`
* `PUT`
* `DELETE`

... und die etwas Exotischeren:

* `OPTIONS`
* `HEAD`
* `PATCH`
