How this service works
Inspects the TLS/SSL certificate of any HTTPS host. Returns validity window (not-before, not-after, days remaining), issuer (CA name, organization), subject (CN), Subject Alternative Names, SHA-256 fingerprint, serial number, and an expiry status (HEALTHY/OK/WARNING/CRITICAL/EXPIRED). Useful for monitoring certificate expiry, auditing TLS configuration, and verifying SAN coverage.
Output
Returns structured SSL/TLS certificate data for the queried host, including certificate subject, issuer, validity period (not-before/not-after dates), SAN entries, and other TLS metadata extracted from the live handshake.
Example use cases
Example prompt
“Can you pull the SSL certificate details for github.com on port 443 — I want to see who issued it and when it expires?”
Technical details
Endpoint
GEThttps://the-stall.intuitek.ai/cap/ssl-certWhen to prefer
Use this endpoint when you need to programmatically inspect the live SSL/TLS certificate of any hostname or IP without an API key or account. Ideal for agents performing security audits, monitoring certificate expiry, verifying issuer chains, or checking SNI-specific certificates on multi-domain servers. Prefer this over manual browser inspection when automating checks across many domains.
Side effects
- Host unreachable or DNS resolution failure — connection error returned
- Port not open or not running TLS — handshake failure
- Invalid hostname format — input validation error
- Certificate self-signed or chain broken — may still return cert data with error flags
- Timeout if host is slow to respond
