# 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 Usage

This tool calls the LinkFox tool gateway API. See `references/api.md` for calling conventions, request parameters, and response structure. You can also execute `scripts/ebay_search.py` directly to run queries.

## Usage Examples

**1. Basic Keyword Search**
Search for "wireless earbuds" on the US eBay marketplace:
```json
{"keyword": "wireless earbuds"}
```

**2. Search Sold Listings for Price Research**
Find sold listings for "iPhone 15 Pro" to gauge market value:
```json
{"keyword": "iPhone 15 Pro", "showOnly": "Sold,Complete", "orderBy": "10"}
```

**3. Search on a Specific Marketplace with Price Range**
Find new laptops priced between $500 and $1000 on eBay UK:
```json
{"keyword": "laptop", "ebayDomain": "ebay.co.uk", "priceMin": 500, "priceMax": 1000, "itemCondition": "1000"}
```

**4. Auction Items Ending Soon**
Find active auctions for "vintage watch" ending soonest:

```

**8. Location-Filtered Search**
Find products located in Germany on the German eBay site:
```json
{"keyword": "Kopfhoerer", "ebayDomain": "ebay.de", "location": 77}
```

## 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

## Handling Large Responses

To avoid overflowing the agent context, persist the response to disk and extract only the fields you need:

```
python scripts/response_io.py run --script scripts/ebay_search.py --out-dir <DIR> '<params>'
python scripts/response_io.py read <file> --fields "<paths>"   # or --path "<JMESPath>"
```

> Pick `--out-dir` outside any git working tree (e.g. `/tmp/...` on Unix, `%TEMP%/...` on Windows). Persisted responses may contain PII, pricing, or auth-sensitive data — do not commit them. Files are not auto-deleted; clean up when the task is done.

`run` writes the full response to a file and emits only a schema preview + file path. `read` projects specific fields, with `--limit/--offset` for slicing and `--format json|jsonl|csv|table` for output.

**When to prefer this pattern** — apply your judgment based on the response characteristics, e.g.:
- High field count per record, or fields you don't need
- Batch/paginated results (multiple items per call)
- Long-text fields (descriptions, reviews, HTML, time series)
- Output reused across later steps rather than consumed immediately

For small, single-use responses, calling the main script directly is fine.

⚠️ The preview is a truncated schema + sample, not the full data. Any field-level decision must read from the persisted file via `read`.
