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 vouch for each other. Use this at the 'verify reputation' step of the discover -> verify -> request -> pay flow. Free and read-only. By Crest Deployment Systems LLC.

Skills

• Verify counterparty reputation
  Verify a counterparty before you pay it: is this AI agent or x402 service real, trustworthy, and settlement-backed, or a scam or ghost? Given a wallet (0x...) or domain, returns its 0-1000 AgentRank reputation and trust score from real on-chain USDC settlement (sybil-resistant, not gameable feedback), a verdict, USDC settled, and payer count. Use before settling an x402 payment, extending credit, or trusting another agent.
