## Deprecate a *path operation* { #deprecate-a-path-operation }

If you need to mark a *path operation* as <abbr title="obsolete, recommended not to use it">deprecated</abbr>, but without removing it, pass the parameter `deprecated`:

    * The same way that Starlette uses Uvicorn and cannot be faster than it, **FastAPI** uses Starlette, so it cannot be faster than it.
    * FastAPI provides more features on top of Starlette. Features that you almost always need when building APIs, like data validation and serialization. And by using it, you get automatic documentation for free (the automatic documentation doesn't even add overhead to running applications, it is generated on startup).
