    message: str


app = FastAPI()


@app.get(
    "/items/{item_id}",
    response_model=Item,
    responses={
        404: {"model": Message, "description": "The item was not found"},
        200: {
            "description": "Item requested by ID",
            "content": {
                "application/json": {
                    "example": {"id": "bar", "value": "The bar tenders"}
                }

在此情況下 **FastAPI** 會期望如下的主體：

```JSON hl_lines="2"
{
    "item": {
        "name": "Foo",
        "description": "The pretender",
        "price": 42.0,
        "tax": 3.2
    }
}
```

而不是：

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2
}
```

                * `description`: A short description of the tag.
                    [CommonMark syntax](https://commonmark.org/) MAY be used for rich
                    text representation.
                * `externalDocs`: Additional external documentation for this tag. If
                    provided, it would contain a `dict` with:
                    * `description`: A short description of the target documentation.

        td = document.createElement("td");
        tr.appendChild(td);
        td.appendChild(document.createTextNode("Description"));

        for (MethodDoc methodDoc : methods) {
            // <tr>
            //   <td><literal><link linkend="$id">$name</link>$signature</literal></td>
            //   <td>$description</td>
            // </tr>
            tr = document.createElement("tr");
            parent.appendChild(tr);

FastAPI достатньо розумний (насправді, Pydantic достатньо розумний), щоб зрозуміти, що, хоча `description`, `tax` і `tags` мають ті самі значення, що й типові, їх було встановлено явно (а не взято як значення за замовчуванням).
