你可以設定下列欄位，這些欄位會用在 OpenAPI 規格與自動產生的 API 文件介面中：

| 參數 | 型別 | 說明 |
|------------|------|-------------|
| `title` | `str` | API 的標題。 |
| `summary` | `str` | API 的簡短摘要。<small>自 OpenAPI 3.1.0、FastAPI 0.99.0 起可用。</small> |
| `description` | `str` | API 的簡短說明。可使用 Markdown。 |
| `version` | `string` | API 的版本號。這是你自己的應用程式版本，不是 OpenAPI 的版本，例如 `2.5.0`。 |
| `terms_of_service` | `str` | 指向 API 服務條款的 URL。若提供，必須是 URL。 |
