How Brand Book works

Manual brand-by-brand checks are how accounts get flagged.

Most sellers find out what they can list by trial-listing — and miss the brands they didn't think to try. Brand Book asks Amazon's official Listings Restrictions API directly, sampling real ASINs across all 64,000 brands, and hands you a complete approved-vs-gated-vs-invite list. You expand your catalog. You don't risk your storefront.
