Resale IQ is an independent market-intelligence service for people who buy and resell second-hand clothing and other fashion items. Using public Vinted listing data across France, Germany, Spain, Italy, and Portugal, it tracks more than 14 million listing records and provides signals for selected brands and models. Each item check gives a BUY, WATCH, or SKIP verdict, a typical asking price, and a buy-below price to help resellers assess what to pay before sourcing stock.

The service covers brands including Nike, Adidas, Levi’s, Zara, and Gucci, with free checks for examples such as Adidas Samba, Nike Air Force 1, and Fred Perry Polo. Resale IQ offers 10 monthly item checks at no charge; paid plans add higher check limits, weekly buy lists, watchlists, and planning tools. Its free resources include fee and profit calculators, listing photo support, size conversion, lot valuation, a profit-tracking template, and a Chrome extension.

Resale IQ also publishes market data, guides, and information for sellers using multiple resale platforms
