# HTTP Security Headers Analyzer

> HTTP Security Headers Analyzer is a paid API for AI agents from domain-email-intel.laboutique.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-18).

Fetches and grades a website's HTTP security headers, returning a score, letter grade, and actionable findings about missing or misconfigured headers.

## Facts

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 http-security-headers-analyzer-6da6b6d2
```

Example prompt: Can you audit the security headers for https://example.com and tell me what grade it gets, what's missing, and what I should fix first?

## When to prefer this

Use this endpoint when you need a fast, structured security header grade and actionable findings for any public URL — especially useful for pre-launch audits, vendor assessments, or compliance checks. Prefer this over manual curl inspection when you need a scored, categorized report with per-header advice rather than raw header dumps.

## Known failure modes

- Unreachable or invalid URL returns an error or non-200 status
- Sites with strict bot-blocking may return incomplete header data
- Paywalled or authentication-gated URLs may only reflect the login page headers
- Redirect chains may cause unexpected final URL analysis
- Rate limiting or network timeouts for slow external servers

Pay-per-call domain, email and website intelligence for AI agents (x402, USDC on Base). Free demos under /demo/<endpoint>.

## Output

A JSON object containing the checked URL, a letter grade (e.g. 'C'), a numeric score (0–100), HTTP status code, a list of findings with per-header advice and presence status, any cookie security issues, detected version leaks in headers, and whether HTTP redirects to HTTPS.
