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。

解决认证和积分问题

发生以下异常情况时，采用 references/onboarding.md 引导解决问题：

异常情况

• 未配置API Key：环境变量未配置 LINKFOX_AGENT_API_KEY，也未配置 LINKFOXAGENT_API_KEY。
• 响应401或402状态码
• 响应提示积分或余额不足：消息含"积分余额不足/计费不足/余额不足/quota exceeded/insufficient balance/套餐到期/需充值/请充值"，或类似含义的内容。

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:

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.
