How this service works
Call when an agent needs a TLS certificate summary for a public host or URL (private IPs blocked). Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/ssl-check first.
Output
A structured summary of the TLS/SSL certificate for the queried public host or URL, including details such as the issuer, subject, subject alternative names (SANs), validity period (not-before / not-after dates), whether the certificate is currently valid, and certificate chain information.
Example use cases
Pre-launch HTTPS audit
“Before we go live, check the SSL certificate for api.mycompany.com — I need to know the issuer, expiry date, and whether it's currently trusted.”
Monitor competitor cert expiry
“Look up the TLS certificate for stripe.com and tell me when it expires and who signed it.”
Diagnose HTTPS warning on client site
“A client is getting browser SSL warnings for shop.examplestore.com — can you fetch the certificate details so I can see what's wrong with it?”

Endpoint
POSThttps://agentshelf.syntexa.ch/v1/ssl-check?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs to programmatically retrieve and inspect TLS certificate metadata for a public hostname or URL without writing custom network code. It is particularly useful for security audits, expiry monitoring, and HTTPS diagnostics on public-facing infrastructure. Prefer the free sandbox endpoint (/v1/sandbox/ssl-check) for testing; use this paid endpoint ($0.004 USDC) for production use cases where reliability and consistent uptime matter.
Side effects
- Private or reserved IP addresses are blocked and will return an error
- Invalid or malformed hostnames/URLs return a validation error
- Hosts with no TLS/no HTTPS will fail to return certificate data
- Network timeouts if the host is unreachable
- Self-signed or otherwise untrusted certs may return partial data with warnings
