See how it works →Paste any product identifier. Find every retailer that sells it.
ASIN, UPC, EAN, or GTIN — any of them work. You get the Amazon listing, the brand, the category, the price, plus every other retailer carrying the same UPC. That's a sourcing-lead list in one click. Same data layer RealArb uses to surface profitable products.

Get the complete list of brands you're allowed to sell.
Brand Book asks Amazon's official Listings Restrictions API directly — sampling up to 10 real ASINs across all 64,000 brands — and hands you a complete approved-vs-gated-vs-invite list. Connect Seller Central with read-only OAuth. We never create a listing.
