# WaveSpeed Image Edit 接口字段

## 协议身份

- 插件 ID：`wavespeed-image-edit`。
- Provider ID：`wavespeed-image-edit`。
- 能力：`image`。
- 默认 Base URL：`https://api.wavespeed.ai/api/v3`。
- 鉴权驱动：`bearer`。
- 创建：`POST /{{model}}`（model 为 WaveSpeed 图片编辑端点，如 `openai/gpt-image-2.5-sunburst/edit`）。
- 生命周期：异步任务（create 返回 task id，poll 轮询结果）。

## 配置字段

| 字段 | 类型 | 必填 | 含义 |
| --- | --- | --- | --- |
| `apiKey` | secret | 是 | WaveSpeed API Key |

## 统一字段映射

| 统一字段 | 类型 | 必填 | 上游映射 | 说明 |
| --- | --- | --- | --- | --- |
| `model` | string | 是 | `model` | WaveSpeed 图片编辑模型端点 ID。 |
| `prompt` | string | 是 | `prompt` | 编辑提示词。 |
| `images` | media[] | 否 | `images` | 编辑源图或参考图，按数组顺序透传 URL。 |
| `imageCount` | integer | 否 | `n/sample_count` | 输出数量（WaveSpeed 多数编辑模型不支持，留空）。 |
| `aspectRatio` | string | 否 | `aspect_ratio` | 比例或尺寸，如 `1:1`、`16:9`。 |
| `resolution` | string | 否 | `resolution/imageSize` | 分辨率档位（编辑模型一般不支持，留空）。 |
| `quality` | string | 否 | `quality` | 质量档位：`low` / `medium` / `high`。 |
| `providerOptions` | object | 否 | `provider-specific fields` | 插件命名空间内的厂商扩展字段。 |

## 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` | `"/{{model}}"` |
| `create.contentType` | `"application/json"` |
| `create.body.prompt` | `{"$ref":"request.prompt"}` |
| `create.body.images` | `{"$map":{"from":{"$ref":"request.images"},"as":"media","in":{"$ref":"media.value"}}}` |
| `create.body.aspect_ratio` | `{"$omitEmpty":{"$ref":"request.aspectRatio"}}` |
| `create.body.quality` | `{"$omitEmpty":{"$ref":"request.quality"}}` |
| `create.body.output_format` | `{"$omitEmpty":{"$coalesce":[{"$ref":"request.providerOptions.wavespeed-image-edit.output_format"},"png"]}}` |
| `create.body.enable_base64_output` | `{"$omitEmpty":{"$ref":"request.providerOptions.wavespeed-image-edit.enable_base64_output"}}` |
| `create.body.enable_sync_mode` | `{"$omitEmpty":{"$ref":"request.providerOptions.wavespeed-image-edit.enable_sync_mode"}}` |
| `poll.method` | `"GET"` |
| `poll.path` | `"/predictions/{{taskId}}/result"`（taskId 来自 create 响应 `data.id`） |
| `poll.contentType` | `"application/json"` |

## Provider 扩展键

- `providerOptions.wavespeed-image-edit.output_format`
- `providerOptions.wavespeed-image-edit.enable_base64_output`
- `providerOptions.wavespeed-image-edit.enable_sync_mode`

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.data.id"},{"$ref":"response.id"}]}` |
| `response.status` | `{"$coalesce":[{"$ref":"response.data.status"},{"$ref":"response.status"},"pending"]}` |
| `response.message` | `{"$coalesce":[{"$ref":"response.data.error"},{"$ref":"response.data.message"},{"$ref":"response.error.message"},{"$ref":"response.message"}]}` |
| `response.images` | `{"$ref":"response.data.outputs"}` |
| `response.errorPaths[0]` | `"error.code"` |
| `response.resultEphemeral` | `true` |

WaveSpeed 异步任务响应结构：

- create 成功：`{"code":200,"data":{"id":"<taskId>"}}`
- poll 进行中：`{"code":200,"data":{"id":"<taskId>","status":"processing","outputs":null}}`
- poll 完成：`{"code":200,"data":{"id":"<taskId>","status":"completed","outputs":["https://cdn.wavespeed.ai/..."]}}`
- poll 失败：`{"code":200,"data":{"id":"<taskId>","status":"failed","error":"..."}}`

`images` 直接透传 `data.outputs` 字符串数组；宿主把每个字符串识别为结果媒体 URL（同时兼容对象数组取 `url` 字段的写法）。`resultEphemeral` 标记临时媒体 URL，由宿主立即下载持久化。

## 兼容边界

模型字段由所选端点决定：编辑类端点接受 `prompt + images[]`；图层分解端点（`bytedance/seedream-v5.0-pro/layer-decomposition`）接受 `image + prompt`（用 `providerOptions` 传额外字段）；去背景端点（`bria/remove-background`）接受 `image`。宿主通过 `request.images` 统一提供源图，模型字段差异由调用方通过 providerOptions 补充。

## 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。
