Припустимо, що тепер файл `main.py` із Вашим **FastAPI**-застосунком містить додаткові операції шляху (**path operations**).

Він має `GET`-операцію, яка може повертати помилку.

Він має `POST`-операцію, яка може повертати кілька помилок.

Обидві операції шляху вимагають заголовок `X-Token`.

The FastAPI counterpart API *path operation* could look like:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():
    return {"message": "Hello World"}
```

See the similarities in `requests.get(...)` and `@app.get(...)`.
