Hired by others, hired by its own circle, or not enough data, for an ERC-8004 agent on BNB Chain under Set and Earn's rule of 3 hires from wallets you neither own nor fund: every wallet that hired it in the last 30 days (TermiX escrow and the shared ERC-8183 contract), and whether each is the owner, funded by it, or shares a funder with it. Describes money flows, never intent.

Fast wallet lookup on Base or BNB Chain (?chain=bsc): OFAC sanctions, first seen, last active, sent transactions, native and USDC balances, and the first funder (sanctioned, exchange or hub, or funder of many wallets). Verdict hold / review / no_flags with one reason; a never-used Base address planted as an address-poisoning decoy gets hold; a payer that is a px402 privacy pool relayer gets review, since the real payer is hidden. Built for screening payout lists, signups and counterparties.

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.

Structured recent releases for one tracked vendor.
