Start Free Trial — 7 Days FreeEvery Haider listing is priced against recent Grailed sold data using time-weighted averaging. Recent sales count more than older ones. We adjust for condition, size, and season. Items below our calculated market value are flagged as deals and sent to subscribers in real-time.
Our 7-signal authentication system checks every listing before alerting — text analysis, price plausibility, seller reputation, image analysis, brand-specific markers, and more. Items scoring below 65% are blocked.
