Grailed

Grailed is a peer-to-peer online marketplace for buying, selling, and discovering luxury, designer, vintage, and streetwear fashion for both men and women. Founded in 2013 and owned by GOAT Group, the platform lets independent sellers list clothing, footwear, accessories, and jewelry while Grailed facilitates the transaction, offering digital listing verification by trained moderators, purchase protection on qualifying orders, secure third-party payment processing (card, PayPal, Apple Pay, Klarna), and a community trust and seller-rating system. Grailed does not publish a public developer API; it exposes a consumer web and mobile experience, an agent-facing /llms.txt, and a RFC 9116 security.txt with a bug bounty program. This profile was surfaced as a portfolio company of Index Ventures and enriched by the API Evangelist pipeline.

Grailed is profiled on the APIs.io network. Tagged areas include Company, Retail, Fashion, Marketplace, and E-Commerce.

Grailed’s developer surface includes support, signup flow, and 9 more developer resources.
