* Periksa jika ada parameter *query* opsional bernama `q` (seperti `http://127.0.0.1:8000/items/foo?q=somequery`) untuk permintaan `GET`.
    * Karena parameter `q` dideklarasikan dengan `= None`, maka bersifat opsional.
    * Tanpa `None` maka akan menjadi wajib ada (seperti struktur di kondisi dengan `PUT`).
* Untuk permintaan `PUT` `/items/{item_id}`, membaca struktur sebagai JSON:
    * Memeriksa terdapat atribut wajib `name` harus berjenis `str`.

## Keuntungan basis-standar, dokumentasi alternatif

Karena skema yang dibuat berasal dari standar <a href="https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md" class="external-link" target="_blank">OpenAPI</a>, maka banyak alat lain yang kompatibel.
