## 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:

//// tab | Python 3.10+

```Python hl_lines="10"
{!> ../../docs_src/path_params_numeric_validations/tutorial001_an_py310.py!}
```
