Catawiki Publishes Its Expert Estimates in the Page JSON. I Built a Deal Finder on Top

Catawiki, an auction site, shares its category experts' estimated value ranges for each lot in the page's JSON data, making this crucial information readily accessible. A developer created a bot to compare current bids against these expert estimates, identifying undervalued lots across categories. This innovation offers savvy bidders a powerful tool to find deals, highlighting a clever use of data transparency by Catawiki. It underscores the potential for leveraging publicly available data to enhance user experience and drive more informed purchasing decisions.
