# Bot Bazaar Security Headers Audit

> Bot Bazaar Security Headers Audit is a paid API for AI agents from bot-bazaar.fly.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).

Audits a URL's HTTP security headers (HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy) and returns an A-to-C security posture grade.

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 bot-bazaar-security-headers-audit-b71e0f91
```

Example prompt: Can you audit the security headers on https://example.com and give me a grade on how well it's protected — specifically checking HSTS, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy?

## When to prefer this

Choose this endpoint when you need a quick, standardized audit of the four core HTTP security headers (HSTS, X-Content-Type-Options, X-Frame-Options, Referrer-Policy) on any publicly accessible URL and want a simple letter-grade summary (A–C). It is ideal for pre-launch checks, vendor due diligence, or automated compliance monitoring pipelines where a lightweight, pay-per-call approach ($0.01 USDC via x402) is preferred over a full-blown security scanner.

## Known failure modes

- Target URL is unreachable or returns a timeout — audit cannot be completed
- Invalid HTTP method supplied (only GET, HEAD, DELETE accepted)
- Target URL redirects in a loop preventing header inspection
- Headers are present but misconfigured — still graded but flagged
- Rate limiting or payment failure prevents the call from completing

## How this service works

Audit HSTS, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy headers and compute an A-to-C security posture grade.

## Output

A structured report indicating the presence and configuration of HSTS, X-Content-Type-Options, X-Frame-Options, and Referrer-Policy headers on the target URL, along with an overall security posture letter grade ranging from A (best) to C (worst).
