Run a live x402 endpoint readiness check before payment

Live x402 endpoint readiness check before payment. This x402 paid API verification service helps verify an x402 endpoint before an AI agent pays: probe one public paid API and inspect the HTTP 402 challenge, payTo address, price, Base USDC network and asset, manifest freshness, buyer budget, and spend policy. Returns ALLOW or DENY with reasons, readiness score, report ID, settlement metadata, and a settlement-backed SHA-256 evidence receipt. Run free can-pay and readiness checks first. Readiness evidence is not a safety guarantee.
