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.

How to call
- API endpoint：
POST /ebay/search(for full parameters/responses/error codes, seereferences/api.md） - Python script：
python scripts/ebay_search.py '<JSON 参数>' [--inline] - Cost constraints: This tool consumes compute; by default, the same parameter combination in the same session is called only once, and the script has a 24h local cache. On failure/empty results, do not automatically switch keywords, paginate, or change the zip code to probe repeatedly; if continued searching is needed, first explain to the user that additional consumption will be incurred.
Output strategy (default script behavior)：
- Alwayswrite the complete response to
<cwd>/linkfox/<YYYY-MM-DD>/<session>/data/linkfox-ebay-search-<timestamp>.json（<cwd>is the working directory when the script runs, which in Claude Code is the current project directory;<session>is taken from the environment variableSESSION_ID, automatically aggregated according to the user's task;writing to /tmp is prohibited; if the current directory is not writable, report an error) - Response body ≤ 8 KB: after writing to disk, print the complete JSON to stdout
- Response body > 8 KB: after writing to disk, stdout outputs only a summary (top-level fields, common counts such as
total/costToken, length of the largest list field + first 3 samples) - Add
--inlineto force full printing to stdout (also written to disk)
Data reading suggestions: first look at the summary to determine whether it is sufficient; when specific fields are needed, prefer to use jqorConvertFrom-Json to extract on demand from the saved json file, avoiding bringing the entire JSON into context.
