<a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">'X-'プレフィックスを使用</a>してカスタムの独自ヘッダーを追加できます。

You can achieve that using <a href="https://docs.pydantic.dev/latest/concepts/validators/#field-after-validator" class="external-link" target="_blank">Pydantic's `AfterValidator`</a> inside of `Annotated`.

FastAPI uses Pydantic model's `.dict()` with <a href="https://docs.pydantic.dev/1.10/usage/exporting_models/#modeldict" class="external-link" target="_blank">its `exclude_unset` parameter</a> to achieve this.

You can also use:

* `response_model_exclude_defaults=True`
* `response_model_exclude_none=True`

O FastAPI usa `.dict()` do modelo Pydantic com <a href="https://docs.pydantic.dev/1.10/usage/exporting_models/#modeldict" class="external-link" target="_blank">seu parâmetro `exclude_unset`</a> para chegar a isso.
