DashScope Wan 3.0 Video 接口字段\n\n## 协议身份\n\n- 插件 ID：`dashscope-wan3-video`。\n- Provider ID：`dashscope-wan3-video`。\n- 能力：`video`。\n- 默认 Base URL：`https://dashscope.aliyuncs.com`。\n- 鉴权驱动：`bearer`。\n- 创建：`POST /api/v1/services/aigc/video-generation/video-synthesis`。\n- 查询：`GET /api/v1/tasks/{{taskId}}`。\n\n## 配置字段\n\n| 字段 | 类型 | 必填 | 含义 |\n| --- | --- | --- | --- |\n| `apiKey` | secret | 是 | API

`images` | media[] | 否 | `first/last/reference image` | 显式 role 图片输入。 |\n| `videos` | media[] | 否 | `reference video` | 参考视频。 |\n| `audios` | media[] | 否 | `reference audio/voice` | 参考音频或音色。 |\n| `duration` | integer | 否 | `duration/seconds` | 时长秒数。 |\n| `aspectRatio` | string | 否 | `ratio/aspect_ratio/size` | 画幅比例或尺寸。 |\n| `resolution` | string | 否 | `resolution` | 分辨率档位。 |\n| `generateAudio` | boolean | 否 | `generate_audio` | 是否生成音频。 |\n| `watermark` | boolean | 否 | `watermark` | 水印开关。 |\n| `providerOptions` | object | 否 | `provider-specific fields` | 插件命名空间内的厂商扩展字段。 |\n\n## 上游请求模板逐字段清单\n\n下表由插件请求模板生成，覆盖 body、query、headers 和 multipart 文件声明中的每个字段。\n\n| 上游位置 | 值或转换表达式 |\n| --- | --- |\n| `create.method` | `\"POST\"` |\n| `create.path` |

URL 标记为 ephemeral，由宿主立即下载持久化。HTTP 错误、业务 code 和 error object 保持失败语义，不包装成成功。\n\n## 兼容边界\n\n该包只代表上述线协议 profile；同一品牌的其他 endpoint、云区域或网关包装必须使用独立插件，不能根据模型名猜测。\n\n<!-- YINGCE_MANIFEST_CONTRACT_START -->\n## Manifest 完整接口定义\n\n以下 JSON 与插件包内实际 `manifest.json` 逐字段一致，覆盖插件身份、权限、配置、鉴权、参数、校验、创建、Agent、查询、取消、结果下载、响应和 Agent 响应映射。`documentation` 字段的值就是当前完整文档；为避免文档在自身内部无限递归，JSON 中仅用等义占位文本表示正文。\n\n```json\n{\n
