What it does

Connects to each host and reads its certificate: issuer, subject, valid-from/to.
Computes days to expiry and flags certs expiring soon or already expired.
Reports whether the chain is valid/trusted and lists the SAN hostnames.

Use cases

Ops & SRE — monitor cert expiry across all domains; prevent outages.
Agencies / MSPs — track certificates for many client sites at once.
Security — audit TLS validity and coverage in bulk.

Input

{ "hosts": ["apify.com", "api.yoursite.com"], "port": 443, "warnDays": 30 }

Field	Type	Description
`hosts`	array	Domains/hosts to check.
`port`	integer	TLS port (default 443).
`warnDays`	integer	Flag certs expiring within this many days.

Output

{ "host": "apify.com", "issuer": "Let's Encrypt", "validTo": "2026-11-01T00:00:00.000Z", "daysLeft": 77, "expiringSoon": false, "valid": true }

Output schema

Field	Type	Description
`host`	string	The domain checked.
`issuer`	string	Certificate issuer.
`daysLeft`	integer	Days until expiry.
`valid`	boolean	Whether the certificate is currently valid and trusted.

FAQ

Can I get alerted? Run it on a schedule and use a webhook/integration to alert when expiringSoon is true.

Can I automate it? Yes — via integrations on the Apify platform and the Apify API.

Notes

Original clean-room implementation.
