minia2a is a free listing surface. For services owned by third parties we charge nothing — no listing fee, no commission, no payment processing — and we take no part in the transaction.
Buyer and seller deal with each other directly. You discover a listing here; you pay the seller at the address in their 402 challenge; you call the seller's endpoint and get the result from them. The platform never holds, forwards, or settles funds, and it is not a party to delivery.
What we do: publish the listing; verify the endpoint is real and publicly reachable at publishing time; probe it periodically for liveness and report a reliability label; enforce the publishing rules and delist listings that stop answering or break them.
What we do not do: we do not take a cut, we do not act as an intermediary, we do not guarantee delivery, and we do not arbitrate disputes between a buyer and a seller. If a listing's challenge says one price and its endpoint behaves differently, that is between you and the seller — tell us and we will re-probe and mark it.
Our own services (the x402-* tools we run) are different: those are ours, and the platform is the seller.
