How this service works
TLS certificate expiry API: days until any domain's certificate expires, plus issuer, subject, SANs, and validity status — even for already-broken certs. The check monitoring agents run daily.
Output
Returns the number of days until the certificate expires, the certificate issuer, subject, Subject Alternative Names (SANs), and the current validity status — including details even when the certificate is already broken or expired.
Example use cases
Example prompt
“Can you check when the TLS certificate for api.stripe.com is going to expire, and also tell me who issued it and what SANs are listed on it?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/tls-cert-expiryWhen to prefer
Use this endpoint when you need to programmatically check TLS certificate expiry, inspect certificate metadata (issuer, SANs, subject), or validate SSL health — especially for monitoring workflows or when dealing with already-broken or expired certificates that other tools may refuse to inspect.
Side effects
- Domain does not exist or is unreachable — connection error returned
- Domain has no TLS certificate (HTTP-only) — no certificate data available
- Certificate is self-signed or uses an unrecognized CA — may still return partial data
- Malformed domain input — validation error
- Network timeout reaching the target host
