x402
OrionCMD TLS Certificate Check is a paid API for AI agents from orioncmd-checks-mcp.dario-9fa.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-27).
Looks up a domain's TLS certificate details from Certificate Transparency logs, including issuer, expiry, days remaining, lifetime usage, renewal stall detection, and a live HTTPS probe.

How this service works
Pay-per-call website checks for agents: TLS certificate (from CT logs), DNS/email-auth, domain expiry, and a site-health bundle. Also available as an MCP server at /mcp.
Output
Returns a JSON object containing: the queried host, whether a cert was found in CT logs, the data source attribution, newest certificate details (issuer, days_left, not_after timestamp, pct_lifetime_used), a renewal_stall suspected flag, and a live_https_probe result with HTTP status code and TLS handshake success indicator.
Example use cases
Pre-launch SSL certificate audit
“Before we go live tomorrow, check the TLS certificate for app.mycompany.com — tell me the issuer, how many days are left, and whether HTTPS is responding correctly.”
Monitoring renewal stall detection
“I'm worried our cert renewal script might have broken — can you check if the certificate for api.acmecorp.com shows any sign of a renewal stall and when it's set to expire?”
Third-party vendor security check
“We're about to integrate with a new vendor — can you pull the certificate transparency info for payments.vendorsite.io and tell me who issued their cert and what percentage of its lifetime has been used?”
Technical details
Endpoint
GEThttps://orioncmd-checks-mcp.dario-9fa.workers.dev/v1/cert?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need TLS certificate metadata sourced from Certificate Transparency logs rather than the live served certificate — ideal for auditing, monitoring expiry, detecting renewal stalls, or verifying a domain's HTTPS health without needing direct certificate negotiation. Particularly useful for agents that need a cheap ($0.01) per-call check without setting up infrastructure.
Side effects
- Domain not found in CT logs — returns found: false with no certificate data
- Invalid or malformed domain input — likely returns an error or empty result
- Domain with no public CT log entries (very rare or brand-new domain) — may return no data
- Live HTTPS probe failure — handshake_ok: false or non-200 HTTP status if site is down
- Rate limit or payment failure — HTTP 402 if payment not provided, or service error
