* Validate that the `item_id` is of type `int` for `GET` and `PUT` requests.
    * If it is not, the client will see a useful, clear error.
* Check if there is an optional query parameter named `q` (as in `http://127.0.0.1:8000/items/foo?q=somequery`) for `GET` requests.

### Using the SDK { #using-the-sdk }

Now you can import and use the client code. It could look like this, notice that you get autocompletion for the methods:

You will also get autocompletion for the payload to send:
