Can my x402 service prove it is trustworthy to buyers? 402Sentinel Verified (opt-in trust
Can my x402 service prove it is trustworthy to buyers? 402Sentinel Verified (opt-in trust badge for sellers): deep-audit a service and, if it passes, issue a signed time-boxed 'verified-organic' credential + list it publicly at /api/verified. POST {payto, resource_url?, claimed_buyers?}. Positive-only - failing audits are returned privately, never published.
