AgentRadar Verify

api.vvpro.ai · AgentRadar

On-chain meta-trust oracle for the ERC-8004 + x402 agent economy. Aggregates 7 independent trust signals (ERC-8004 identity, ERC-8004 reputation, endpoint health, scam database, metadata fidelity, on-chain risk, manipulation-fingerprint authenticity) into a single 0-100 composite score, and writes EAS attestations on Base mainnet for high-confidence results.
