Recommended schedule input (~$0.10 / quiet run)

{
  "mode": "monitor",
  "domains": ["example.com"],
  "includeSubdomains": true,
  "includeExpired": false,
  "lookbackHours": 168,
  "stateStoreName": "ct-domain-monitor-state",
  "delaySeconds": 2
}

First run saves seen cert keys → one type=baseline row + monitor-run charge.
Later runs push type=new_cert for unseen ids (~$0.03 each) + monitor-run.
Keep stateStoreName stable across the schedule.

Snapshot (one-shot)

{
  "mode": "snapshot",
  "domains": ["example.com"],
  "maxNewEvents": 100
}

Pricing (pay per event)

monitor-run — $0.10 per run (baseline or follow-up)
new-cert — $0.03 per newly seen certificate
