Certification Criteria

Ontario Certified x402

Ontario certification is earned from the verification graph: signed report integrity, latest readiness grade, score, freshness, and repeated successful reports. Agents should treat this profile as audit evidence, not as a decorative badge.

Trust Boundary

Ontario Protocol provides readiness and trust signals based on observable endpoint behavior, manifest metadata, payment challenge behavior, report history, and public evidence. It does not guarantee endpoint safety, service quality, financial outcome, or future behavior. Agents should still enforce budget, policy review, and independent verification before spending.
