## Declarar metadatos { #declare-metadata }

Puedes declarar todos los mismos parámetros que para `Query`.

Por ejemplo, para declarar un valor de metadato `title` para el parámetro de path `item_id` puedes escribir:

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

## Verwenden von `Annotated` im Typ für den `q`-Parameter { #use-annotated-in-the-type-for-the-q-parameter }

Erinnern Sie sich, dass ich Ihnen zuvor in [Python-Typen-Intro](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank} gesagt habe, dass `Annotated` verwendet werden kann, um Metadaten zu Ihren Parametern hinzuzufügen?

Jetzt ist es soweit, dies mit FastAPI zu verwenden. 🚀

Lembra que eu disse antes que `Annotated` pode ser usado para adicionar metadados aos seus parâmetros na [Introdução aos tipos do Python](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank}?

Agora é a hora de usá-lo com FastAPI. 🚀

Tínhamos esta anotação de tipo:
