Preflight before paying an x402 service: is it working right now, and did it work the past 30 days? One live probe of the exact resource URL you intend to pay (status, latency, x402 validity, the payTo/price the service itself publishes in its 402, manifest presence) plus our own monitoring history of the host (30-day uptime, last check, recent changes such as payTo or price drift). Optionally verifies that the pay_to you intend to pay matches the live 402. Facts only — no scores.Overview
