Search Certificate Transparency logs for certificates covering a domain

Price: 1 credit

💡 AI Hint: Search Certificate Transparency logs for all certificates issued for a domain. Returns each certificate’s common name, the full list of covered domains (Subject Alternative Names), issuer name, serial number, validity window (not before / not after), and when it was logged. Use a % wildcard in the domain (e.g. %.example.com) to surface subdomains — the primary tool for subdomain and certificate reconnaissance. A domain with no certificates returns an empty list.
