# MiniMax H3 / H3 Max 调用示例

This file is the focused AI-readable context for one UniAI documentation page.

URL: https://docs.uniai.tv/models/video/minimax-h3/examples
Locale: zh-CN
Markdown: https://docs.uniai.tv/ai/pages/models/video/minimax-h3/examples.md
Description: MiniMax H3、H3 Max 视频生成、媒体参考、Context 和 2K 再生成的原生 API 请求示例。

Agent guidance:
- Use this page when the user is asking about this specific route or model capability.
- Preserve endpoint paths, JSON keys, model IDs, and placeholder values exactly.
- `{BASE_URL}` means `https://api.uniai.tv`; treat `sk-***` and `task_xxx` as safe placeholders, not real secrets.

## Page Markdown

将 `$UNIAI_API_KEY` 和素材地址替换为你自己的值。每次发送一个请求。

## Context

返回处理后的提示词，不会创建视频。省略 `resolution`。

```bash
curl -X POST "https://api.uniai.tv/v2/h3_context_ir" \
  -H "Authorization: Bearer $UNIAI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "MiniMax-H3",
    "content": [
      {
        "type": "text",
        "text": "A paper boat crosses a quiet pond in warm morning light."
      }
    ],
    "duration": 5,
    "ratio": "16:9"
  }'
```

## 再生成 2K

使用自己账号最近七天内创建的已完成 H3 768P 任务。

```bash
curl -X POST "https://api.uniai.tv/v2/video_regeneration" \
  -H "Authorization: Bearer $UNIAI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "MiniMax-H3",
    "source_task_id": "task_YOUR_COMPLETED_H3_768P",
    "resolution": "2K"
  }'
```
