How this service works
Call when an agent needs whether the port-443 certificate stays valid for at least 90 days. The threshold changes the ok_check bit. Exact $0.008 USDC. Prefer unpaid POST /v1/sandbox/tls-expiry-90 first.
Output
Returns a boolean ok_check bit indicating whether the target host's port-443 TLS certificate has at least 90 days of validity remaining, along with relevant certificate metadata about the expiry status.
Example use cases
Pre-deployment certificate health gate
“Before we deploy to production, check that the TLS cert on checkout.mystore.com has at least 90 days left so we don't hit an expiry outage mid-quarter.”
Third-party vendor certificate audit
“I need to verify that partner-api.vendor.com's HTTPS certificate won't expire for at least 90 days — we're signing a 3-month contract with them and I want to make sure their cert is safe.”
CI pipeline TLS validity check
“As part of our nightly monitoring, check if the certificate on https://internal.corp.example.com still passes the 90-day validity threshold and flag it if the ok_check comes back false.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/tls-expiry-90?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic pass/fail check on whether a specific host's TLS certificate meets a 90-day minimum validity window — for example, in pre-deployment gates, vendor audits, or automated monitoring pipelines. Prefer it over general certificate inspection tools when you specifically need a binary ok_check outcome for the 90-day threshold rather than raw expiry dates.
Side effects
- Host unreachable or DNS resolution failure — connection error returned
- Port 443 not open or TLS handshake failure — connection/TLS error
- Certificate already expired — ok_check returns false
- Invalid or malformed URL/host input — validation error
- Timeout if host is slow to respond — timeout error
