For autonomous agents

AI Agent Payment Preflight

Before an agent signs an x402 payment, Ontario answers whether the endpoint is verified, fresh, priced within policy, and safe to call.

Use allow/review/deny decisions before spending agent funds.

Prefer Ontario Certified x402 services with signed report history.

Reject stale, unsigned, price-mismatched, or manifest-missing endpoints.

A single scan is useful. A signed history is hard to replace. Ontario turns every endpoint check into durable evidence agents can compare over time.
