Lollipuff

Lollipuff is a luxury goods authentication service that has been authenticating high-end designer apparel and accessories professionally since 2010. Led by CEO Fei Deyle, the company uses a patent-pending process combining human expert authenticators with software to determine the authenticity of pre-owned designer items from submitted photographs, issuing an online certificate with a unique, shareable URL that owners can post alongside listings on sites like eBay. Lollipuff (YC W13) originally operated as a peer-to-peer online auction marketplace that pre-screened every listing for authenticity; the marketplace closed in 2020 as payment-processor fee structures changed, and the company now focuses on its photo-based authentication and certificate-lookup service, which many consignment and resale businesses rely on for their most challenging authentications. It is a consumer-facing web service with no publicly documented developer API.

Lollipuff is profiled on the APIs.io network. Tagged areas include Company, Authentication, Luxury Goods, Designer Fashion, and Resale.

Lollipuff’s developer surface includes engineering blog, support, and 5 more developer resources.
