Ontario Live x402 Endpoint Readiness Check

Verify an x402 endpoint before an AI agent pays: get ALLOW or DENY with reasons, a readiness score, report ID and a settlement-backed SHA-256 evidence receipt. This x402 paid API verification service probes the HTTP 402 challenge, payTo, price, Base USDC network and asset, manifest freshness, budget and spend policy. Run free can-pay and readiness checks first. Readiness evidence is not a safety guarantee.
