Answer "where should I sell this?" for one item. For each US marketplace: whether it accepts the item under its published policies (prohibited and restricted items, condition rules, approval-only categories), the fees and profit at the expected price, the lowest price that meets an optional profit goal, and when the seller gets paid. Every rule cites the official page. Returns picks (highest profit, best margin, fastest payout), ranked marketplaces, ones needing approval, and excluded ones with reasons. Doesn't model demand or the price buyers will pay.
