Every used item worth buying. One place.
Koqi gathers every legitimate used listing in America — from every marketplace, dealer and auction — into one honest search. If it's for sale, you can find it here. If it's here, it's actually for sale. We merge duplicates, close dead listings fast, and show what items really sell for — so buyers can trust what they see, and sellers reach everyone at once.
Buying used in America is broken in a quiet way: the same item is listed in five places, three of the listings are already sold, and the asking price tells you nothing about what the last one actually sold for. Sellers get a fraction of the audience they should, and buyers learn not to trust what they see.
Koqi exists to fix that — not with another marketplace of its own, but with one honest index of all of them. Each category gets a specialist site where its listings live and stay canonical; Koqi is the umbrella above them: one search, one account, one standard of honesty across the whole network.
Every source in one search — not just one marketplace's own listings. eBay, Facebook, Craigslist, dealers and auctions, gathered together.
Listings are verified live, and dead ones are closed quickly. What you see on Koqi is actually still for sale.
Sold-price history sits next to asking prices, so you can see what things really sell for — not just what sellers hope for.
Every listing links back to its seller. Koqi never inserts itself into the deal — you talk to the seller, always.
A listing is never duplicated across the network. The category site is its home; Koqi links to it. That keeps search clean, keeps the seller's page authoritative, and means the network never competes with itself.
Every listing. Every marketplace. One search.
