Powering internal pricing tools with the Trendful Catalog API
Peer-to-peer resale has revolutionized the way people buy and sell secondhand fashion. Platforms like eBay, Poshmark, Vinted, and Vestiaire Collective have made it easy for anyone, from average day people to professional sellers, to participate in the resale economy. With just a few clicks, you can list an item, ship it, and get paid. For buyers, it’s become a popular way to discover everything from luxury bags to vintage streetwear at a fraction of the original price. But while these platforms have lowered the barriers to entry, they’ve also introduced friction. Product discovery is often chaotic. Prices for similar luxury pre-owned items may vary dramatically, creating outliers in pricing. In addition, titles are vague, descriptions are inconsistent, and search results are often overwhelming. Whether you’re buying or selling, navigating peer-to-peer resale can be frustrating.
