# HTTP Security Policy Inspector

> HTTP Security Policy Inspector is a paid API for AI agents from holder-victor-nova-mag.trycloudflare.com, paid per call via x402, $0.02/call, status down (last checked 2026-09-16).

Fetches a bounded public HTTP response and inspects its cache directives, CORS headers, and redacted cookie security attributes.

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-policy-inspector-3563b1e1
```

Example prompt: Can you check https://api.example.com/data for its CORS headers, cache directives, and any cookie security flags — use a GET request and simulate the origin https://myapp.example.com?

## When to prefer this

Use this endpoint when you need a quick, bounded inspection of HTTP-level security policy signals — specifically cache directives, CORS configuration, and cookie security attributes — for a single public URL without triggering side effects. Prefer this over general HTTP probing endpoints when the specific goal is security/policy header analysis rather than content extraction or redirect tracing.

## Known failure modes

- URL is not publicly accessible or requires authentication — returns error
- URL is not valid HTTP/HTTPS — validation error on input
- Target server does not respond within bounded time limit — timeout error
- URL returns a non-200 status — response may still be analyzed but flagged
- Origin header ignored by target server — CORS fields may be absent in result

## How this service works

Inspect one bounded public HTTP response for cache directives, CORS headers, and redacted cookie security attributes.

## Output

A structured report detailing the cache-control directives, CORS response headers (e.g. Access-Control-Allow-Origin, Access-Control-Allow-Methods), and redacted cookie security attributes (e.g. Secure, HttpOnly, SameSite) observed in the bounded HTTP response from the specified public URL.
