TLS/SSL Certificate Inspector
x402
TLS/SSL Certificate Inspector is a paid API for AI agents from twin.unykorn.org, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-02).
Checks a hostname's TLS/SSL certificate and returns issuer, expiry date, days remaining, SANs, trust status, and protocol version

How this service works
TLS/SSL certificate check: issuer, expiry, days left, SANs, trust, protocol — Genesis402 / UnyKorn Operator Network
Output
Returns structured details about the hostname's TLS/SSL certificate including the certificate issuer (CA name), expiry date and timestamp, number of days remaining until expiry, Subject Alternative Names (SANs) listing all covered domains, whether the certificate chain is trusted, and the TLS/SSL protocol version in use.
Example use cases
Pre-deployment certificate audit
“Before we go live, check the SSL cert on staging.myapp.io — tell me the issuer, expiry date, days left, and whether the certificate is trusted.”
Certificate expiry monitoring alert
“Check the TLS certificate for mail.company.com and tell me how many days are left before it expires — I want to know if we're at risk of it lapsing soon.”
Security review of third-party vendor
“We're vetting a new payment processor at checkout.vendorsite.com — can you pull the SSL certificate details including the issuer, SANs, trust status, and which TLS protocol version they're running?”
Technical details
Endpoint
POSThttps://twin.unykorn.org/web/tls-cert?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically inspect TLS/SSL certificate details for any hostname — particularly for certificate expiry monitoring, security audits, compliance checks, or verifying SANs coverage. It is ideal for AI agents that need structured certificate metadata (issuer, days left, SANs, trust, protocol) without spinning up custom TLS inspection tooling. Prefer this over manual certificate checks or generic web scraping when you need machine-readable certificate data at low cost ($0.002/call).
Side effects
- Host not reachable or DNS resolution failure for the provided hostname
- Host does not support TLS/SSL (plain HTTP only)
- Self-signed or untrusted certificate that cannot be verified
- Connection timeout when the host is slow to respond
- Invalid or malformed hostname input
- Certificate already expired — returned with 0 or negative days remaining
