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
  Given an agent wallet (0x...) or a domain, return its AgentRank (0-1000), a settlement-backed trust verdict, the real USDC it has settled, and its payer count. 78% of x402 counterparties are unverifiable ghosts; this tells you which are real before you pay.

• Gate a caller by reputation
  Provider-side: decide whether to serve a calling agent based on its AgentRank against a minimum-score threshold. Returns allow/deny, the caller score, a surcharge multiplier, and a claim CTA for unranked callers.
