# Powerboy856 x402 URL Audit

> Powerboy856 x402 URL Audit is a paid API for AI agents from powerboy856-x402-tools.cesarsr1420.chatgpt.site, paid per call via x402, $0.25/call, status unknown (last checked 2026-09-14).

Fetches a given HTTPS URL and returns a deterministic audit report including HTTP status, page title, SHA-256 content hash, security headers, content type, and byte count.

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 powerboy856-x402-url-audit-f721bf83 -d '<json body>'
```

Example prompt: Can you audit https://example.com/ and tell me its HTTP status, page title, SHA-256 hash, and whether it has Strict-Transport-Security enabled?

## When to prefer this

Use this endpoint when you need a lightweight, deterministic, single-URL audit that returns a bundle of HTTP diagnostics (status, title, hash, security headers, byte count, final URL) in one call. It is ideal for content integrity checks, security header verification, redirect tracing, and page fingerprinting without requiring a full browser rendering pipeline or a heavyweight scraping service.

## Known failure modes

- Non-HTTPS URLs are rejected by schema pattern validation
- URLs exceeding 2048 characters are rejected
- Unreachable or timed-out URLs may return ok: false or an error response
- Paywalled or bot-blocked pages may return partial or unexpected content
- Redirects to non-HTTPS final URLs may behave unexpectedly

## How this service works

Small, deterministic API tools paid per call with USDC on Base through x402.

## Output

A JSON object containing: ok (boolean), title (page title string), sha256 (hex digest of content), status (HTTP status code), finalUrl (URL after any redirects), bytesRead (integer), contentType (MIME type string), and securityHeaders (object with flags like strictTransportSecurity).
