TrustAgent

Is this counterparty safe to transact with — to pay, or to accept payment from? Screens the address against the OFAC sanctions list, then SYBIL-FILTERS its ERC-8004 reputation: reviewers are clustered by first funding source and capped at one vote per cluster, so manufactured feedback from wallets funded out of one purse counts once. Returns an explainable 0-100 trust score with a proceed / hold / block recommendation, and reports insufficient_data rather than guessing when the evidence is not there. Free alternative: GET /v1/verify. Trial: 3 free calls/wallet/24h — https://trust-agent.io/v1/trial.
