בחזרה לדוגמאת הקוד הקודמת, **FastAPI** ידאג:

-   לאמת שיש `item_id` בנתיב בבקשות `GET` ו - `PUT`.
-   לאמת שה - `item_id` הוא מטיפוס `int` בבקשות `GET` ו - `PUT`.
    -   אם הוא לא, הלקוח יראה שגיאה ברורה ושימושית.
-   לבדוק האם קיים פרמטר שאילתא בשם `q` (קרי `http://127.0.0.1:8000/items/foo?q=somequery`) לבקשות `GET`.
    -   מאחר והפרמטר `q` מוגדר עם <code dir="ltr"> = None</code>, הוא אופציונלי.
