x402 APIPassing, checked 31 min ago

Silent-death watcher for scheduled agent jobs — submit job history (name, cadence, run timestamps, last success) and get gap analysis, stale flags, and a SILENT_DEATH_RISK score per job with recommended checks. Stateless analysis of submitted history only — it does not watch anything itself ($0.05). Toll: $0.05 USDC on Base or Solana.
