基于已有图 + prompt **改写整张图**。适合背景替换、风格迁移、内容修改。

| 项目 | 内容 |
| - | - |
| action | `EDITS` |
| 计费 | `midjourney@edits[-speed]` |
| 必填 | `prompt` + `image_urls` |

## 参数

| 字段 | 类型 | 必填 | 说明 |
| - | - | - | - |
| `prompt` | string | 是 | 编辑指令 |
| `nsfw_check` | boolean | 否 | 默认值为 `false`。 提交 Midjourney 任务前执行内容审核。 • `true`：使用 `omni-moderation-latest` 审核提示词和输入图片 • `false`：跳过审核，不增加审核成本与延迟 |
| `image_urls` | string\[] | 是 | 待编辑图；单图 ≤ 12 MiB |
| `speed` | string | 否 | 默认: `relax`; `relax` / `fast` / `turbo` |
| `metadata` | object | 否 | 自定义元数据 |

### 结构化参数（可选）

同 [Imagine](https://docs.apimart.ai/cn/api-reference/images/midjourney/imagine.md)，可写在 body 里或 prompt 中（如 `--ar 16:9`），body 优先级高于 prompt，会拼到 prompt 末尾并覆盖同名手写 flag。

| 字段 | 类型 | 等价 MJ 参数 | 说明 |
| - | - | - | - |
| `size` | string | `--ar` | 宽高比，如 `"16:9"`, `"1:1"`, `"9:16"` |
| `quality` | string | `--q` | 质量：`"0.25"`, `"0.5"`, `"1"`, `"2"` |
| `style` | string | `--style` | 风格：`"raw"` 等 |
| `version` | string | `--v` | 版本号。主版本会追加为 `--v <version>`；与 `niji: true` 搭配 `"7"` / `"6"` 时会归一化为 Niji 版本 |
| `seed` | int | `--seed` | 随机种子 |
| `negative_prompt` | string | `--no` | 负面提示词，如 `"ugly, blurry"` |
| `stylize` | int | `--s` | 风格化强度 (0-1000) |
| `chaos` | int | `--c` | 混乱度 (0-100) |
| `weird` | int | `--w` | 怪异度 (0-3000) |
| `tile` | bool | `--tile` | 平铺模式 |
| `niji` | bool | `--niji` | Niji 开关。推荐传 `niji: true` + `version: "7"` / `"6"` |
| `iw` | float | `--iw` | 图片权重 (0-3)，垫图时使用 |
| `cw` | int | `--cw` | 角色权重 (0-100) |
| `sw` | int | `--sw` | 风格权重 (0-1000) |
| `cref` | string | `--cref` | 角色参考图 URL |
| `sref` | string | `--sref` | 风格参考图 URL |
| `dref` | string | `--dref` | 深度参考图 URL |
| `dw` | float | `--dw` | 深度权重 (0-100) |
| `repeat` | int | `--repeat` | 重复生成次数 (2-40) |
| `raw` | bool | `--raw` | 原始风格 (v5.1+ 支持) |
| `draft` | bool | `--draft` | 草图模式 (v7+ 支持) |
| `hd` | bool | `--hd` | HD 高清 (仅 v8.1 / v8.2，未传 version 时后端自动补 `--v 8.1`) |
| `stop` | int | `--stop` | 提前停止 (10-100，仅 v5-6.1 / niji 5-6) |
| `extra` | string | 任意 `--xxx` | 逃生口，原样追加到 prompt 末尾 |

## 请求示例

```json theme={null}
{
  "prompt": "replace the background with a modern kitchen, keep the product unchanged --ar 1:1",
  "image_urls": ["https://example.com/product.png"],
  "version": "8.1",
  "speed": "fast"
}
```

## 响应

提交返回 `task_id`，SUCCESS 后含编辑结果 `image_urls`（可能 1–4 张）+ `grid_image_url`。

## 注意

* 与 imagine 垫图的区别：edits 重在"改写整张图"，imagine + 垫图重在"参考风格"。
* 缺 `prompt` 或 `image_urls` 返回 `400`；单图超 12 MiB 返回 `400`。
