SSL Certificate Lookup
POST

SSL Certificate Lookup API — fetches the live TLS certificate chain presented by a domain. Each certificate reports its validity window, serial number, signature algorithm, subject and issuer, public-key algorithm and size, key usages, and the full list of SAN hostnames the certificate covers. Use valid_to for expiry monitoring and san_dns_names to confirm a certificate actually covers the host you are serving. Raw PEM blocks are omitted — the parsed fields carry the same information in usable form.

  • Global coverage
  • Real-time domain intelligence and analysis lookup
  • Structured JSON response
  • POST request with Bearer auth
