 *       {@link #last})
 *   <li>query methods which answer questions about the {@code FluentIterable}'s contents (for

8. Notice that this *path operation function* uses regular `def` instead of `async def`.

    As always, in FastAPI you can combine `def` and `async def` as needed.

    If you need a refresher about when to use which, check out the section _"In a hurry?"_ in the docs about [`async` and `await`](../async.md#in-a-hurry).

9. This *path operation function* is not returning dataclasses (although it could), but a list of dictionaries with internal data.

If you needed to, you could use settings and environment variables to configure OpenAPI conditionally depending on the environment, and even disable it entirely.

## About security, APIs, and docs { #about-security-apis-and-docs }

Hiding your documentation user interfaces in production *shouldn't* be the way to protect your API.

By setting `--proxy-headers` now FastAPI would be able to redirect to the right location. 😎
