## Type hints in **FastAPI** { #type-hints-in-fastapi }

**FastAPI** takes advantage of these type hints to do several things.

With **FastAPI** you declare parameters with type hints and you get:

* **Editor support**.
* **Type checks**.

...and **FastAPI** uses the same declarations to:

It had automatic data validation, data serialization and OpenAPI schema generation based on the same type hints in several places.

  /**
   * The HTTP <a href="https://wicg.github.io/ua-client-hints/#sec-ch-ua">{@code Sec-CH-UA}</a>
   * header field name.
   *
   * @since 30.0

  public static final String SEC_CH_UA = "Sec-CH-UA";

## Investigation { #investigation }

By using all the previous alternatives I had the chance to learn from all of them, take ideas, and combine them in the best way I could find for myself and the teams of developers I have worked with.

For example, it was clear that ideally it should be based on standard Python type hints.

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

## `fastapi-slim`

⚠️ Do not install this package. ⚠️

This package, `fastapi-slim`, does nothing other than depend on `fastapi`.

All the functionality has been integrated into `fastapi`.
