How this service works
Call when an agent needs whether the port-443 certificate stays valid for at least 7 days. The threshold changes the ok_check bit. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/tls-expiry-7 first.
Output
Returns an ok_check boolean indicating whether the port-443 TLS certificate for the given host is valid for at least 7 days. A true value means the certificate is safe; false means it expires within the 7-day threshold or is already invalid.
Example use cases
Pre-deployment certificate health check
“Before we deploy tonight, check whether the SSL certificate on staging.myapp.com is going to stay valid for at least 7 more days.”
Automated site reliability monitoring
“Check if the TLS certificate on our production domain store.mybusiness.com is safe from expiring within the next week — I want to know the ok_check result.”
Third-party API dependency audit
“I rely on payments.partnerservice.io — can you verify their port-443 certificate won't expire within 7 days so I know it's safe to keep using them?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/tls-expiry-7?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick binary yes/no on whether a TLS certificate will remain valid for at least 7 days, specifically against the port-443 threshold check. Prefer this over a full certificate detail lookup when you only need the expiry safety signal and not raw certificate metadata. It is purpose-built for automated monitoring pipelines and pre-deployment checks where a simple ok_check flag is sufficient.
Side effects
- Host unreachable or DNS resolution failure — returns error indicating connection could not be established
- Certificate already expired — ok_check returns false
- Invalid or malformed host/URL input — validation error returned
- Port 443 not open or TLS handshake fails — connection error
- Payment not satisfied — HTTP 402 returned before processing
