## 调用方式

- **API 端点**：`POST /alibaba1688/imageSearch`（完整参数/响应/错误码见 `references/api.md`）
- **Python 脚本**：`python scripts/alibaba1688_image_search.py '<JSON 参数>' [--inline]`
- **成本约束**：本工具会消耗积分；同一会话同一参数组合默认只调用一次，脚本带 24h 本地缓存。失败/空结果不得自动换关键词、翻页或改邮编连续试探；需要继续检索时先向用户说明会产生额外消耗。

**输出策略（脚本默认行为）**：
- **始终**将完整响应写入 `<cwd>/linkfox/<YYYY-MM-DD>/<session>/data/linkfox-1688-search-by-image-<timestamp>.json`（`<cwd>` 为脚本执行时的工作目录，在 Claude Code 里即当前项目目录；`<session>` 取自环境变量 `SESSION_ID`，按用户任务自动聚合；**禁止写入 /tmp**，当前目录不可写则报错）
- 响应体 ≤ 8 KB：落盘后把完整 JSON 打印到 stdout
- 响应体 > 8 KB：落盘后 stdout 只输出摘要（顶层字段、常见计数如 `total`/`costToken`、最大列表字段的长度 + 前 3 条样本）
- 加 `--inline` 强制全量打印到 stdout（同样落盘）

**读数据建议**：先看摘要判断是否足够；需要具体字段时优先用 `jq`或`ConvertFrom-Json` 从保存的 json 文件按需抽取，避免整份 JSON 进入上下文。

## Local Image Upload

This tool requires a **publicly accessible image URL**. If the user provides a local image file path, you must upload it first to obtain a public URL.

Run the upload script:
```bash
python scripts/upload_image.py /path/to/local/image.png
```

The script will return a public URL (valid for 24 hours) that can be used as the imageUrl parameter.

## Usage Examples

**1. Basic image search**
```
在1688搜索与图片相似的商品，图片地址为 https://m.media-amazon.com/images/I/719mRAn2VrL._AC_SL1500_.jpg
```

**2. Search with filters**
```
在1688搜索与图片相似的商品，图片地址为 https://m.media-amazon.com/images/I/719mRAn2VrL._AC_SL1500_.jpg，查询第1页，筛选1688严选，并按价格从高到低排序
```

**3. Search with sorting**
```
在1688搜索与图片相似的商品，图片地址为 https://example.com/product.jpg，按价格从高到低排序
```

**4. Paginated search**
```
在1688搜索与图片相似的商品，图片地址为 https://example.com/product.jpg，查询第2页，每页50条
```

**5. Price range filter**
```
在1688搜索与图片相似的商品，图片地址为 https://example.com/product.jpg，价格区间10-100元
```

## Display Rules

1. **Present data clearly**: Show results in a structured table with key columns: product image, title, price, dropship price, monthly sales, minimum order quantity, repurchase rate, and seller identity
2. **Image display**: When the response includes imageUrl for products, display them inline for visual comparison
3. **Price display**: Always show price in CNY (¥) format
4. **Seller badges**: Display seller identity badges (超级工厂/实力商家/诚信通会员) and product badges (严选) prominently
5. **Result count**: Always inform the user of total results and current page/total pages
6. **Pagination hint**: When more pages are available, suggest the user can request the next page
7. **Filter/sort limitation**: If the user requests a sort or filter not in the supported list, do NOT attempt any workaround. Inform the user of the supported options
8. **No secondary processing**: Results are real-time and not stored in a database, so secondary SQL/data processing is not available

## Important Limitations

1. **Data real-time nature**: Results are live searches, not stored in any database. Cannot use `_dataQuery_executeDynamicQuery` for secondary processing.
2. **Logic constraint**: If the user requests sort or filter conditions not in the preset supported list, do NOT call any other tool or logic to compensate.
3. **Image input**: One of imageUrl, imageBase64, or imageId is required. For page > 1, prefer passing imageId from the first page result to speed up queries.
4. **Image format**: Only png, jpg, jpeg are supported. webp, gif, and other formats will be rejected.
5. **Base64 format**: The imageBase64 value must be the raw Base64 string only — do NOT include the `data:image/jpeg;base64,` prefix.
6. **Page size**: Maximum 50 results per page.
