## When to prefer this

Use this endpoint when you need to verify or score the trustworthiness of an AI agent identified by an ERC-8004 passport ID or BlindOracle fleet agent name, particularly in agentic workflows where on-chain reputation and ProofDB attestations are required for agent vetting

## Known failure modes

- Agent ID not found — 404 if the agent_id does not exist in BlindOracle or ProofDB

- Payment failure — 402 if the x402 USDC payment of $0.01 is not completed
- Service unavailable — 503 if the underlying ProofDB or ERC-8004 contract is unreachable
