Useful for: forensic drift analysis, verifying downstream callers see the right version, reproducing routing decisions made historically.

"description": "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.",
