## Metadata para la API

Puedes establecer los siguientes campos que se usan en la especificación OpenAPI y en las interfaces automáticas de documentación de la API:

| Parámetro | Tipo | Descripción |
|------------|------|-------------|
| `title` | `str` | El título de la API. |
| `summary` | `str` | Un resumen corto de la API. <small>Disponible desde OpenAPI 3.1.0, FastAPI 0.99.0.</small> |

    /**
     *
     * @return the name type
     */
    @Override
    public int getNameType() {
        return this.hexCode;
    }

    /**
     * Constructs a NetBIOS name with the specified parameters.
     *
     * @param cfg the configuration to use
     * @param name the NetBIOS name (will be truncated to 15 characters if longer)
     * @param hexCode the NetBIOS name type code

Commençons avec cette application pour exemple :

{* ../../docs_src/query_params_str_validations/tutorial001.py hl[9] *}

Le paramètre de requête `q` a pour type `Union[str, None]` (ou `str | None` en Python 3.10), signifiant qu'il est de type `str` mais pourrait aussi être égal à `None`, et bien sûr, la valeur par défaut est `None`, donc **FastAPI** saura qu'il n'est pas requis.

/// note

/// tip

This is just standard Python, it's called a "type alias", it's actually not specific to **FastAPI**.

But because **FastAPI** is based on the Python standards, including `Annotated`, you can use this trick in your code. 😎

///

                "item_id"
            ],
            "msg": "value is not a valid integer",
            "type": "type_error.integer"
        }
    ]
}
```

obtendrás una versión en texto, con:

```
1 validation error
path -> item_id
  value is not a valid integer (type=type_error.integer)
```

#### `RequestValidationError` vs `ValidationError`

/// warning | Advertencia

                "item_id"
            ],
            "msg": "value is not a valid integer",
            "type": "type_error.integer"
        }
    ]
}
```

você receberá a versão em texto:

```
1 validation error
path -> item_id
  value is not a valid integer (type=type_error.integer)
```

### `RequestValidationError` vs `ValidationError`
