```

The query parameter `q` is of type `Union[str, None]` (or `str | None` in Python 3.10), that means that it's of type `str` but could also be `None`, and indeed, the default value is `None`, so FastAPI will know it's not required.

!!! note
    FastAPI will know that the value of `q` is not required because of the default value `= None`.

{"item_id": 5, "q": "somequery"}
```

כבר יצרתם API ש:

-   מקבל בקשות HTTP בנתיבים `/` ו - <code dir="ltr">/items/{item_id}</code>.
-   שני ה _נתיבים_ מקבלים _בקשות_ `GET` (ידועות גם כ*מתודות* HTTP).
-   ה _נתיב_ <code dir="ltr">/items/{item_id}</code> כולל \*פרמטר נתיב\_ `item_id` שאמור להיות `int`.
-   ה _נתיב_ <code dir="ltr">/items/{item_id}</code> \*פרמטר שאילתא\_ אופציונלי `q`.
