# SEE2AI 图像生成 · Pro 2K

> SEE2AI premium 2K image generation with optional ordered reference images, durable asynchronous delivery, and SEE2AI-hosted results.

## 📖 接入指引

**Endpoint**: `POST /api/v1/actions/see2ai_image_generation_pro_v2`

**认证方式**: Bearer Token (租户 API Key)

**Recommended production path**: `POST /api/v1/actions/see2ai_image_generation_pro_v2/async`

> Recommended for production integrations because premium 2K image jobs complete asynchronously and return stable hosted results through polling.

### Endpoints

| Method | Path | Purpose |
| --- | --- | --- |
| `POST` | `/api/v1/actions/see2ai_image_generation_pro_v2` | Submit the standard action request. |
| `POST` | `/api/v1/actions/see2ai_image_generation_pro_v2/async` | Submit an asynchronous premium 2K image job. Returns `task_id` and initial `status`. |
| `GET` | `/api/v1/actions/see2ai_image_generation_pro_v2/status/{task_id}` | Poll the premium 2K image job. When completed, read the final image from `result_urls`. |

### Async Result Flow

1. Submit the generation request and save the returned `task_id`.
2. Poll `GET /api/v1/actions/see2ai_image_generation_pro_v2/status/{task_id}` with the same API key until the task reaches a terminal status.
3. Read the final artifact URL from the status response. Use `image_url` for UniWorld and `result_urls` for image/video actions.

> **⚠️ 重要提示**
> 
> 本 API 是 SEE2AI 平台标准化封装后的接口，**参数格式与任何上游 API 不同**。
> 请直接使用下方 Schema 中定义的参数，无需参考其他文档。
> 
> *例如：*
> *- 文本模型参数可能是 `query` 而不是 `messages` 数组*
> *- 视频模型参数可能是 `brief` (创意简报) 而不是复杂的配置项*
