Overview

Check SSL/TLS certificates for a list of domains — issuer, validity dates, days to expiry, covered hostnames and chain problems — so you catch expiring certificates before they cause an outage. Run it on a schedule and monitor every domain you own.

SSL Certificate Expiry Checker input — configure the options in the Apify Console

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).

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