• AI agent reputation score (ERC-8004)
  Returns a 0-100 reputation score for any AI agent active onchain on Base. Score = success rate 50% + USDC settlement volume 30% + recency 20%. Aggregates ERC-8004 ReputationRegistry feedback, and x402 settlement volume/success rate. Free preview returns score + verdict; full profile requires an ERC-8004 attestation or a $0.05 USDC live re-score. For buyer/orchestrator agents vetting a service provider before paying.
