Check SSL certificate & domain expiry
Look up a website's SSL certificate expiry (date, days left, issuer), domain registration expiry (date, days left, registrar) and current HTTP status. Use when someone asks when a site's certificate or domain expires, who issued it, or whether the site is up. "warn" means expiring within 30 days, "bad" means expired or down. Results are cached for 15 minutes; fresh lookups are limited to 15 per 10 minutes.
