How this service works
HTTPS certificate inspector: retrieves the full TLS certificate detail for any domain, including the subject-alternative-name list and whether the certificate currently validates. Deliberately still returns data for expired or broken certificates so monitoring tools can flag exactly what is wrong. For security screening and scheduled compliance checks.
Output
Returns the full TLS certificate detail for the queried domain, including the subject alternative name (SAN) list, certificate validity status (valid, expired, or broken), issuer, expiry date, and any certificate errors — even for expired or misconfigured certificates so monitoring tools can identify exact issues.
Example use cases
Example prompt
“Can you pull the full TLS certificate details for api.stripe.com — I want to see whether it's currently valid, when it expires, and what domains are listed in the subject alternative names?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/https-certificate-lookupWhen to prefer
Use this endpoint when you need programmatic access to raw TLS certificate metadata for any domain, especially for security monitoring, compliance audits, or alerting on expired/broken certificates. It is distinct from simple SSL checkers because it deliberately returns data even for invalid or expired certificates, enabling precise fault diagnosis rather than a simple pass/fail result.
Side effects
- Domain does not exist or is unreachable — may return an error or empty response
- Network timeout when attempting to connect to target domain
- Malformed hostname input causing a validation error
- Domain exists but has no HTTPS listener — certificate retrieval fails
