⚪scan_deals(query, buying_option, min_discount_pct, min_price, ending_within_hours, ...)
Scan live eBay listings for a product and return the ones priced furthest under the current market median. AUCTION mode (default) finds ending-soon auctions sitting under market; FIXED_PRICE mode finds mispriced Buy It Now listings that can be bought instantly. Includes market median, percent under market, and a buy link per result.
