Por exemplo, no modelo `Image` nós temos um campo `url`, nós podemos declara-lo como um `HttpUrl` do Pydantic invés de como uma `str`:

```Python hl_lines="4  10"
{!../../docs_src/body_nested_models/tutorial005.py!}
```

A string será verificada para se tornar uma URL válida e documentada no esquema JSON/1OpenAPI como tal.
