Looks up each domain in Certificate Transparency logs (the public crt.sh
JSON API — no key needed) and reports the currently valid certificates: how
many are live right now, the one expiring soonest (soonestNotAfter +
daysUntilExpiry), its issuer, and all Subject Alternative Names it covers.
Boolean flags expiringWithin30Days / 60 / 90 make it trivial to filter
or alert on. Up to 10 individual valid certificates are listed per domain with
their validity windows and crt.sh IDs.
Schedule it monthly and watch daysUntilExpiry shrink — if it drops below 30
without a fresh cert appearing, your renewal automation is broken.
