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.

API Invocation

• API Endpoint: POST /ebay/search (full parameters/response/error codes in references/api.md)
• Python Script: python scripts/ebay_search.py ''<JSON params>'' [--inline]
• Cost: This tool consumes credits. The same parameter combination is only called once per session by default; the script has a 24h local cache. Do not automatically retry with different keywords, pages, or zip codes on failure/empty results. If further retrieval is needed, explain the additional cost to the user first.

Output Strategy (script default behavior):

• Always write the full response to <cwd>/nexscope/<YYYY-MM-DD>/<session>/data/nexscope-ebay-search-<timestamp>.json (<cwd> is the working directory at script execution time, i.e. the current project directory in Claude Code; <session> comes from the SESSION_ID environment variable, automatically grouped by user task; do not write to /tmp, error out if the current directory is not writable)
• Response body <= 8 KB: print the full JSON to stdout after writing to disk
• Response body > 8 KB: after writing to disk, stdout only outputs a summary (top-level fields, common counts like total/costToken, length of the largest list field + first 3 samples)
• Add --inline to force full output to stdout (still writes to disk)

Data Reading Tips: Check the summary first to see if it is sufficient. When specific fields are needed, prefer using jq or ConvertFrom-Json to extract from the saved JSON file on demand, avoiding loading the entire JSON into context.

Authentication

Set the NEXSCOPE_API_KEY environment variable. If authentication fails (401/402) or you see insufficient balance errors, visit https://www.nexscope.ai/help/skills-external-access?co-from=skillNS to get an API Key or top up credits.

Usage Examples

3. Search on a Specific Marketplace with Price Range Find new laptops priced between $500 and $1000 on eBay UK:

Display Rules

1. Present data clearly: Show search results in well-formatted tables including key fields such as title, price, condition, seller info, and shipping
2. Price formatting: Always display prices with their currency symbol. When showing price ranges (minPrice to maxPrice), format as a range
3. Sold/completed data: When showing sold items, highlight the sold price and quantity to help users with pricing research
4. Seller trust indicators: When available, show seller feedback percentage and review count to help users evaluate seller reliability
5. Pagination notice: When total results exceed the current page, inform the user of the total count and suggest pagination to see more
6. Sponsored items: Clearly mark sponsored listings so users can distinguish organic results from promoted ones
7. Error handling: When a query fails, explain the issue and suggest adjusting search parameters
8. Link presentation: Provide product links so users can view full details on eBay

Important Limitations

• No historical data: This tool returns current live listings only, not historical pricing trends
• Result cap: Maximum 200 results per page
• Rate limiting: Excessive requests may be throttled; use noCache: true sparingly
• Currency: Prices are returned in the local currency of the eBay domain being searched
