## Sponsor the author { #sponsor-the-author }

If your **product/company** depends on or is related to **FastAPI** and you want to reach its users, you can sponsor the author (me) through [GitHub sponsors](https://github.com/sponsors/tiangolo). Depending on the tier, you could get some extra benefits, like a badge in the docs. 🎁

FastAPI is a modern, fast (high-performance), web framework for building APIs with Python based on standard Python type hints.

The key features are:

* **Fast**: Very high performance, on par with **NodeJS** and **Go** (thanks to Starlette and Pydantic). [One of the fastest Python frameworks available](#performance).

## 在 `q` 参数的类型中使用 `Annotated` { #use-annotated-in-the-type-for-the-q-parameter }

还记得我之前在[Python 类型简介](../python-types.md#type-hints-with-metadata-annotations)中说过可以用 `Annotated` 给参数添加元数据吗？

现在正是与 FastAPI 搭配使用它的时候。🚀

我们之前的类型标注是：

```Python
q: str | None = None
```

我们要做的是用 `Annotated` 把它包起来，变成：

```Python
