  • AgentRank

    Settlement-grounded reputation for AI agents. Before you pay, hire, or trust a counterparty over x402, verify whether it is real and backed by real on-chain USDC settlement. AgentRank returns a 0-1000 score that is a recomputable function of settled value weighted by payer reputation, not self-reported feedback, so it cannot be faked by agents that…
