Know before you buy. Know before you sell.

PriceSpecter is a free price research tool for collectors, resellers, and antique dealers. Describe any item and we pull real-time eBay market data — the lowest active price, typical asking price, and full range from what's listed on eBay right now. A Specter Score tells you how reliable the estimate is based on listing volume and price consistency.

Set Flip Alerts on items you're watching and get emailed the moment a listing appears below typical asking. Save items to your Vault to track your collection's estimated worth over time. Use our suggested pricing when listing items directly to eBay.

For resellers working estate sales and flea markets, Rapid Scan mode turns your phone into a mobile appraisal tool — point your camera at any barcode for an instant valuation with automatic flip detection and an audible alert when you've found a deal worth buying. Bulk Search lets you research up to 10 items simultaneously. Seller Watch tracks specific eBay sellers and pings you when they list something new, and Lot Scanner surfaces auction lots with vague titles that hide real collectible value.
