How this service works
Call when an agent needs whether the port-443 certificate stays valid for at least 30 days. The threshold changes the ok_check bit. Exact $0.006 USDC. Prefer unpaid POST /v1/sandbox/tls-expiry-30 first.
Output
Returns an ok_check boolean bit: true if the port-443 TLS certificate for the given host or URL will remain valid for at least 30 days from now, false if it expires sooner or cannot be verified. May also include remaining days until expiry.
Example use cases
Pre-deployment certificate health check
“Before we push to production, verify that the TLS cert on staging.myapp.com will stay valid for at least 30 days — I don't want an expiry surprise right after launch.”
Automated SSL renewal alerting
“Check if the SSL certificate on payments.acme.com is expiring within 30 days so I know whether to trigger a renewal now.”
Third-party vendor certificate audit
“I'm auditing our vendor integrations — can you check whether the certificate on api.vendor-portal.com is still good for the next 30 days?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/tls-expiry-30?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a simple pass/fail check specifically against a 30-day expiry threshold for a TLS certificate on port 443. Prefer this over generic TLS inspection tools when you want a clear boolean ok_check result without parsing raw certificate dates yourself, especially in automated monitoring or pre-deployment pipelines.
Side effects
- Host unreachable or DNS resolution failure — connection error returned
- Certificate already expired — ok_check returns false
- Invalid or malformed hostname/URL input — validation error
- Host does not serve TLS on port 443 — connection or handshake error
- Certificate chain incomplete or untrusted — may return error or false
