SSL Certificate Lookup

Domain Intelligence and Analysis
POST /api/v1/domain/ssl Bearer

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.

What SSL Certificate Lookup Is Used For

Certificate expiry monitoring

Track valid_to across your estate and alert before a certificate lapses and takes a site down.

Coverage verification

Check san_dns_names to confirm a certificate actually covers the hostname you are serving.

Security posture auditing

Review signature algorithm, public key algorithm and key size against your own minimum standard.

Vendor and supplier checks

Inspect the live certificate chain a third party presents before integrating with them.

One-click convenience for testing & troubleshooting — no account needed.

1

What it doesSaves your API key in this browser only using localStorage. Next time you open a docs page, the Try It panel is pre-filled automatically.

2

Auto-updatesIf you type a different key into any Try It field, the saved key is replaced instantly — only the most recent key is ever stored.

3

Uncheck to forgetUnchecking “Remember API Key” immediately deletes the stored key and clears the field. While unchecked, nothing is saved even if you type a new key.

4

Re-check to save againChecking the box again saves whatever key is currently in the Try It field.

⚠ Security note: Your key is stored only in your browser and is never sent to any server except as part of the actual API call you send. Do not use this feature on shared or public computers.
