Technical details
Endpoint
GEThttps://sentineltrust.xyz/v1/reputationWhen to prefer
Use this endpoint when you need an independent, cross-chain reputation signal for an AI agent before delegating tasks, integrating a third-party agent, or making trust-dependent decisions. Prefer this over chain-specific explorers when you need a unified reliability grade backed by security scanning.
Side effects

- Payment not processed — 402 response requiring 0.1 USDC via x402 protocol
- Invalid query parameters — returns 400 bad request
- Unsupported chain or agent type — returns no attestation data
- Rate limiting — repeated calls may be throttled
