## How to call it through Zero

```sh
zero fetch --capability website-security-headers-audit-50915a49 -d '<json body>'
```

Example prompt: Can you audit the security headers for https://example.com and tell me what grade it gets, whether the cookies have the right flags set, and if it's leaking any version or server info?

## When to prefer this

Choose this endpoint when you need a quick, automated HTTP security header audit with a standardized A-F grade, cookie flag inspection, and version-leak detection for any public URL — especially useful for pre-launch checks, compliance reviews, or competitive benchmarking without needing to run your own tooling like securityheaders.com or custom curl scripts.

## Known failure modes

- Non-public or unreachable URLs return an error or timeout
- Private/intranet URLs that are inaccessible from the audit server fail with a connection error
- Malformed URLs result in a validation error
- Sites behind aggressive firewalls or WAFs may block the audit request
- HTTPS sites with invalid certificates may fail or return partial results

## How this service works

Website security-headers audit with A-F grade, cookie flags and version leaks — Genesis402 / UnyKorn Operator Network

## Output
