# OrionCMD SSL/TLS Certificate Check

> OrionCMD SSL/TLS Certificate Check is a paid API for AI agents from api.orioncmd.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-11).

Looks up a domain's SSL/TLS certificate details from Certificate Transparency logs and probes the live HTTPS connection to report issuer, expiry, days remaining, and renewal stall status.

## Facts

- Endpoint: GET https://api.orioncmd.com/v1/cert?utm_source=zero.xyz
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-11
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/orioncmd-ssl-tls-certificate-check-b3e39042
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_7f-Vioqssh0--50Jj9Lcy

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability orioncmd-ssl-tls-certificate-check-b3e39042
```

Example prompt: Can you check the SSL certificate status for mybusiness.com — I want to know who issued it, how many days are left before it expires, and whether the renewal looks stalled?

## When to prefer this

Choose this endpoint when you need a quick, passive SSL/TLS certificate health check for a domain without requiring server-side credentials or intrusive scanning. It is ideal for monitoring expiry timelines, confirming HTTPS connectivity, and detecting renewal stalls using publicly available Certificate Transparency log data combined with a lightweight live probe. Prefer it over full vulnerability scanners when cost, speed, and non-intrusiveness matter.

## Known failure modes

- Domain not found in CT logs — returns found: false with no cert data
- Domain unreachable for live probe — handshake_ok: false or HTTP status error
- Invalid or malformed domain input — likely 400 or empty response
- CT log data may lag real-world cert issuance by minutes to hours
- Payment failure via x402 protocol — 402 response if payment not completed

## How this service works

Passive-first monitoring for uptime, SSL/TLS, DNS, email security, internet exposure, WordPress core advisories, and breach exposure — with reachability probes, optional authorized scans, plain-English alerts, and client-ready reports.

## Output

Returns a JSON object with the host, whether a cert was found, the data source (Certificate Transparency logs via Cert Spotter), newest certificate details (issuer, days left, expiry date, percent lifetime used), a renewal stall flag, and a live HTTPS probe result including HTTP status code and TLS handshake success.
