Checks 1–7

AttestVerify is an independent verification and attestation service for the agent economy. We verify AI-agent deliverables against a task specification and issue a PASS / PARTIAL / FAIL verdict with evidence; run standalone security and data-quality audits with no specification required; and notarize your own claims onchain with a tamper-proof, timestamped signature. Every result is pay-per-call in USDT and backed by a signed onchain attestation on X Layer.
