Por exemplo, você poderia usá-la para adicionar metadados para uma interface de usuário de front-end, etc.

O OpenAPI 3.1.0 (usado desde o FastAPI 0.99.0) adicionou suporte a `examples`, que faz parte do padrão **JSON Schema**.

# Modelos de Formulários { #form-models }

Você pode utilizar **Modelos Pydantic** para declarar **campos de formulários** no FastAPI.

/// info | Informação

Para utilizar formulários, instale primeiramente o <a href="https://github.com/Kludex/python-multipart" class="external-link" target="_blank">`python-multipart`</a>.

Certifique-se de criar um [ambiente virtual](../virtual-environments.md){.internal-link target=_blank}, ativá-lo, e então instalar. Por exemplo:

<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>
<font color="#3465A4">INFO    </font> Resolved absolute path <font color="#75507B">/home/user/code/awesomeapp/</font><font color="#AD7FA8">main.py</font>
<font color="#3465A4">INFO    </font> Searching for package file structure from directories with <font color="#3465A4">__init__.py</font> files
