# OrionCMD HTTP Security Headers Check

> OrionCMD HTTP Security Headers Check is a paid API for AI agents from api.orioncmd.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-13).

Fetches and grades the HTTP security headers of a given domain, returning a letter grade and plain-English findings about missing or misconfigured headers.

## 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-http-security-headers-check-8fb7e7ce
```

Example prompt: Can you check the HTTP security headers for shopify.com and tell me which ones are missing or misconfigured, along with an overall security grade?

## When to prefer this

Use this endpoint when you need a fast, per-domain HTTP security header inspection with an actionable letter grade and plain-English findings — ideal for one-off audits, client reports, or pre-launch checks. Prefer this over full-site scanning tools when you only need header-layer analysis without deep vulnerability scanning or authenticated crawls.

## Known failure modes

- Domain not reachable — endpoint may return an error or empty headers if the target host is down or refuses connections
- Invalid domain format — malformed input may result in a validation error
- Redirects to non-HTTP endpoint — grade may reflect redirect destination rather than origin
- Rate limiting or payment failure — x402 payment not processed correctly may block the request
- Timeout — slow-responding domains may not return headers in time

## 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

A JSON object containing the analyzed hostname, an overall security grade (A–F), a map of key security headers and their values (or null if absent), a list of plain-English findings describing issues, the final resolved URL after redirects, and the HTTP status code of the final response.
