Api Endpoint

ChainWard x402 seller check

Real demand, self-funded demand, mixed or not enough data for an x402 or marketplace seller on Base or BNB Chain (?chain=bsc), with the one number behind it: how much of its top buyers' money traces back to the seller, how much it pays back, whether one wallet funds most buyers. Payers behind facilitator proxies (Meridian, Fluxa) are named on Base. Describes money flows, never intent.
