## 上游请求模板逐字段清单

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。

| 上游位置 | 值或转换表达式 |
| --- | --- |
| `create.method` | `"POST"` |
| `create.path` | `"/api/v1/services/aigc/video-generation/video-synthesis"` |
| `create.contentType` | `"application/json"` |
| `create.body.model` | `{"$ref":"request.model"}` |
| `create.body.input.prompt` | `{"$omitEmpty":{"$ref":"request.prompt"}}` |
| `create.body.input.media` | `{"$omitEmpty":{"$coalesce":[{"$ref":"request.providerOptions.dashscope-wan3-video.media"},{"$map":{"from":{"$sortByOrder":{"$ref":"request.inputs"}},"as":"media","in":{"type":{"$coalesce":[{"$ref":"media.role"},{"$if":{"condition":{"$eq":[{"$ref":"media.kind"},"image"]},"then":"reference_image","else":{"$if":{"condition":{"$eq":[{"$ref":"media.kind"},"video"]},"then":"reference_video","else":{"$if":{"condition":{"$eq":[{"$ref":"media.kind"},"audio"]},"then":"reference_audio","else":{"$ref":"media.kind"}}}}}}}]},"url":{"$ref":"media.value"}}}}]}}` |
| `create.body.parameters.resolution` | `{"$omitEmpty":{"$ref":"request.resolution"}}` |
| `create.body.parameters.ratio` | `{"$omitEmpty":{"$ref":"request.aspectRatio"}}` |
| `create.body.parameters.duration` | `{"$omitEmpty":{"$ref":"request.duration"}}` |
| `create.body.parameters.audio` | `{"$coalesce":[{"$ref":"request.providerOptions.dashscope-wan3-video.audio"},{"$ref":"request.generateAudio"}]}` |
| `create.body.parameters.seed` | `{"$omitEmpty":{"$ref":"request.providerOptions.dashscope-wan3-video.seed"}}` |
| `create.body.parameters.prompt_extend` | `{"$coalesce":[{"$ref":"request.providerOptions.dashscope-wan3-video.prompt_extend"},true]}` |
| `create.body.parameters.watermark` | `{"$ref":"request.watermark"}` |
| `create.headers.X-DashScope-Async` | `"enable"` |
| `poll.method` | `"GET"` |
| `poll.path` | `"/api/v1/tasks/{{taskId}}"` |
| `poll.contentType` | `"application/json"` |

## Provider 扩展键

- `providerOptions.dashscope-wan3-video.audio`
- `providerOptions.dashscope-wan3-video.media`
- `providerOptions.dashscope-wan3-video.prompt_extend`
- `providerOptions.dashscope-wan3-video.seed`

动态模型或工作流允许使用文档声明的完整 `parameters/input/extra_body` 对象；该对象是协议本身的开放 schema，不会被宿主裁剪。

## 响应映射逐字段清单

| 映射位置 | 上游路径或转换表达式 |
| --- | --- |
| `response.taskId` | `{"$coalesce":[{"$ref":"response.output.task_id"},{"$ref":"response.task_id"},{"$ref":"taskId"}]}` |
| `response.status` | `{"$if":{"condition":{"$eq":[{"$lower":{"$ref":"response.output.task_status"}},"unknown"]},"then":"failed","else":{"$coalesce":[{"$ref":"response.output.task_status"},{"$ref":"response.status"},"pending"]}}}` |
| `response.message` | `{"$coalesce":[{"$ref":"response.error.message"},{"$ref":"response.message"},{"$ref":"response.fail_reason"}]}` |
| `response.videos` | `{"$ref":"response.output.video_url"}` |
| `response.errorPaths[0]` | `"code"` |
| `response.errorPaths[1]` | `"output.code"` |
| `response.resultEphemeral` | `true` |
| `response.usage` | `{"$ref":"response.usage"}` |
| `response.messagePaths[0]` | `"message"` |
| `response.messagePaths[1]` | `"output.message"` |

## 响应与错误

插件把上游 task/status/text/media/usage 映射为统一结果。临时媒体 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。

## 兼容边界

Wan 3.0 原生异步视频。模型仅 wan3.0-video-prime / wan3.0-video；input.media 为 type+url；UNKNOWN 视为失败。文档：https://docs.bailian.console.aliyun.com/zh/model-studio/wan3-video-generation-api-reference。

## Manifest 完整接口定义

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。
