## 示例：节日促销海报

生成双十一促销海报：

```bash theme={null}
curl https://api.aigc.it/v1/images/generations \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer <YOUR_TOKEN>" \
  -d '{
    "model": "seedream-4.5",
    "prompt": "Double 11 shopping festival promotional poster, vibrant red and gold colors, gift boxes, shopping bags, festive atmosphere, modern e-commerce style, Chinese festival theme",
    "size": "1080x1920",
    "watermark": false
  }'
```

## 示例：品牌系列素材

批量生成统一风格的品牌素材：

```bash theme={null}
curl https://api.aigc.it/v1/images/generations \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer <YOUR_TOKEN>" \
  -d '{
    "model": "seedream-4.5",
    "prompt": "Generate 3 minimalist brand images for a premium skincare line: 1) product showcase with soft lighting, 2) natural ingredients concept, 3) luxury spa atmosphere. Consistent color palette: white, gold, soft pink.",
    "sequential_image_generation": "auto",
    "sequential_image_generation_options": {
      "max_images": 3
    },
    "size": "2K",
    "stream": true,
    "watermark": false
  }'
```

## 最佳实践

  3. **批量生成**：一次生成多个版本，选择最佳效果
