Make sure you [Upgrade the FastAPI version](../deployment/versions.md#upgrading-the-fastapi-versions) to at least 0.95.1 before using `Annotated`.

///

## Declare metadata { #declare-metadata }

You can declare all the same parameters as for `Query`.

For example, to declare a `title` metadata value for the path parameter `item_id` you can type:

{* ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py hl[10] *}

/// note
