1688 Image-Based Product Search

This skill performs visual product searches on the 1688 platform using an image URL, helping cross-border sellers find visually similar supplier products for sourcing.

Core Concepts

1688 Image Search uses visual recognition to find products with similar appearance on the 1688 wholesale marketplace. It returns supplier product data including title, price, minimum order quantity, monthly sales, repurchase rate, trade score, and seller identity badges.

Data Fields

Parameter Guide

Image Rules:

1. JPEG and PNG are passed through unchanged. WebP is detected from its real file bytes and transparently converted to JPEG before the 1688 call.
2. Base64 string must be pure encoded content WITHOUT the data:image/jpeg;base64, prefix.
3. Image source — one of imageUrl, imageBase64, or imageId must be provided (at least one required).

Supported Filters

Multiple filters can be combined with commas (e.g. 1688Selection,totalEpScoreLv1,qrr0).

Supported Sort Fields

Sort format example: {"price":"asc"} for price low to high.

Supported Product Collection IDs

调用方式

• API 端点：POST /alibaba1688/imageSearch（完整参数/响应/错误码见 references/api.md）
• Python 解释器选择：调用前先选择一个真实可用的 Python 命令并在本次任务中始终复用，记为 <PYTHON>。Windows 按 py -3、python、python3 的顺序尝试，其他系统按 python3、python 的顺序尝试；候选命令必须执行 <候选命令> -c "import sys; print(sys.executable)" 后退出码为 0 且 stdout 含非空解释器路径，否则视为不可用（WindowsApps 的空输出占位命令不得选用）。
• Python 脚本：<PYTHON> scripts/alibaba1688_image_search.py '<JSON 参数>' [--inline]
• 无感图片预处理：必须通过上述脚本调用。JPEG/PNG 保持原逻辑；WebP 由 Agent 使用 Pillow 转成 JPEG 后再按原逻辑调用，不要求用户手工转换。
• Pillow 首次初始化：在当前运行环境第一次调用本 Skill 前，Agent 必须用 <PYTHON> 执行 <PYTHON> -c "from PIL import features; ok=features.check('webp'); print('WEBP_OK' if ok else 'WEBP_MISSING'); raise SystemExit(0 if ok else 1)"。只有退出码为 0 且 stdout 包含 WEBP_OK 才算检查通过。如果检查失败，静默执行 <PYTHON> -m pip install --disable-pip-version-check "Pillow>=10.4,<13"，然后用同一 <PYTHON> 重新检查一次。检查通过后再运行图搜脚本；第二次仍失败时停止并报告依赖初始化失败，不得进入收费接口，也不得循环安装或要求用户手工处理。后续调用检查通过即可直接执行，不重复安装。
• 成本约束：本工具会消耗算力；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。

解决认证和算力问题

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
• 响应提示算力或余额不足：消息含"算力余额不足/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: JPEG/PNG follow the original path. The bundled script transparently converts WebP to JPEG before calling 1688. GIF and other formats retain their original behavior.
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.

User Expression & Scenario Quick Reference

Applicable -- Visual product sourcing scenarios on 1688:

Not applicable -- Needs beyond 1688 image search:

• Text/keyword-based 1688 search (use 店雷达-1688选品库)
• 1688 product rankings/trending (use 店雷达-1688商品榜单)
• Amazon image search (use 亚马逊前端-以图搜图)
• Image generation or editing
• Product review analysis
• Price history or trend analysis

Boundary judgment: When users say "找货源" or "找同款", if they provide an image URL and the intent is to find visually similar products on 1688, this skill applies. If they want keyword-based search or ranking data on 1688, use the 店雷达 tools instead.
