Full reliability report on one x402 service from our own availability monitoring (~2 probes/day per host): daily probe series over 30 days (probes, ok, avg/max latency), uptime 7d/30d, all observed change events (up/down transitions, payTo drift, price drift, manifest appearing/disappearing) and the payment details as last observed in the service's own 402 responses. Returns 400 host_not_monitore…
Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-01).
