SSL Certificate Checker Check the SSL/TLS certificate of any domain — issuer, subject, valid-from/to, days-to-expiry, SANs and protocol — in one bulk call. No API key. Built for developers who need fast, reliable, bulk results without managing servers or proxies.

Features

One structured JSON record per domain.
Bulk + concurrent — process up to 100 domains per run.
No proxy, no browser, no API key — fast and low-cost.
Graceful failures: unreachable inputs return ok: false with an error; the run never crashes.

Input

{"domains": ["github.com", "apify.com"], "maxItems": 100}

Output

One record per domain:

{
  "domain": "github.com",
  "ok": true,
  "issuer": "DigiCert Inc",
  "subject": "github.com",
  "validFrom": "2026-01-01T00:00:00.000Z",
  "validTo": "2027-01-01T00:00:00.000Z",
  "daysToExpiry": 192,
  "expired": false,
  "sans": ["github.com", "www.github.com"],
  "protocol": "TLSv1.3"
}

Who it's for

DevOps monitoring certificate expiry
Security teams auditing TLS
Uptime/monitoring dashboards
Compliance & asset inventory

How to use

Add your domains to the domains input field.
Run the Actor and read one structured record per input from the dataset.
Export as JSON, CSV, or Excel, or call the Actor's API from your backend.

FAQ

Do I need an API key? No. You provide domains; the Actor does the rest. Does it return personal data? No — only public infrastructure/metadata, never personal contact data. What formats can I export? JSON, CSV, and Excel via the dataset, or the Actor API.

Pricing

Pay-per-event: a tiny per-run start fee plus a small per-result charge. You pay only for successful results. See the Pricing tab.
