eBay Product Search

This skill guides you on how to search and retrieve eBay product listing data, helping e-commerce sellers and buyers find products, compare prices, and analyze market trends across eBay's global marketplaces.

Core Concepts

eBay Product Search provides access to eBay's front-end product listing data. It supports keyword-based search with rich filtering options including price range, item condition, buying format, sort order, seller location, and more. Results include product details such as title, price, shipping info, seller rating, sold quantity, and item condition.

Marketplace logic: The ebayDomain parameter controls which regional eBay site is searched. The default is ebay.com (US). When a user refers to a country or region, map it to the corresponding eBay domain (e.g., UK -> ebay.co.uk, Germany -> ebay.de).

Buying format: eBay supports multiple buying formats -- Auction for bid-based listings, BIN (Buy It Now) for fixed-price listings, and BO (Best Offer) for negotiable listings.

调用方式

API 端点：POST /ebay/search（完整参数/响应/错误码见 references/api.md）
Python 脚本：python scripts/ebay_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-ebay-search-<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。
