# Runway Image 接口字段

## 协议身份

- 插件 ID：`runway-image`。
- Provider ID：`runway-image`。
- 能力：`image`。
- 默认 Base URL：`https://api.dev.runwayml.com`。
- 鉴权驱动：`bearer`。
- 创建：`POST /v1/text_to_image`。
- 查询：`GET /v1/tasks/{{taskId}}`。

## 配置字段

| 字段 | 类型 | 必填 | 含义 |
| --- | --- | --- | --- |
| `apiKey` | secret | 是 | 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` | 图片模型 ID。 |
| `prompt` | string | 是 | `prompt` | 图片提示词。 |
| `images` | media[] | 否 | `provider image/reference fields` | 参考图或编辑源图，role 由业务层确定。 |
| `imageCount` | integer | 否 | `n/sample_count` | 输出数量。 |
| `aspectRatio` | string | 否 | `size/aspect_ratio` | 比例或尺寸，语义按协议说明。 |
| `resolution` | string | 否 | `resolution/imageSize` | 分辨率档位。 |
| `quality` | string | 否 | `quality` | 质量档位。 |
| `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` | `"/v1/text_to_image"` |
| `create.contentType` | `"application/json"` |
| `create.body` | `{"$merge":[{"model":{"$ref":"request.model"},"prompt":{"$ref":"request.prompt"},"images":{"$omitEmpty":{"$map":{"from":{"$ref":"request.images"},"as":"media","in":{"$ref":"media.value"}}}},"parameters":{"$omitEmpty":{"$ref":"request.providerOptions.runway-image.parameters"}}},{"$coalesce":[{"$ref":"request.providerOptions.runway-image.body"},{"$ref":"request.providerOptions.runway-image.extra_body"},{}]}]}` |
| `poll.method` | `"GET"` |
| `poll.path` | `"/v1/tasks/{{taskId}}"` |
| `poll.contentType` | `"application/json"` |

## Provider 扩展键

- `providerOptions.runway-image.body`
- `providerOptions.runway-image.extra_body`
- `providerOptions.runway-image.parameters`

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.id"},{"$ref":"response.task_id"},{"$ref":"response.taskId"},{"$ref":"response.data.id"},{"$ref":"taskId"}]}` |
| `response.status` | `{"$coalesce":[{"$ref":"response.status"},{"$ref":"response.state"},{"$ref":"response.data.status"},"pending"]}` |
| `response.message` | `{"$coalesce":[{"$ref":"response.error.message"},{"$ref":"response.message"},{"$ref":"response.fail_reason"}]}` |
| `response.images` | `{"$coalesce":[{"$ref":"response.image_url"},{"$ref":"response.imageUrl"},{"$ref":"response.result_url"},{"$ref":"response.url"},{"$ref":"response.data.image_url"},{"$ref":"response.output.url"}]}` |
| `response.errorPaths[0]` | `"error.code"` |
| `response.resultEphemeral` | `true` |

## 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

该协议的模型级字段变化快或依赖云资源配置。插件固定线协议入口和统一字段，完整厂商对象通过 providerOptions.runway-image 的 parameters/input/extra_body 传入；async Runway image schema。云签名型入口在未配置对应鉴权驱动时会明确失败，不会伪装成 Bearer 成功。

## 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。
