# Creator Desk URL Inspector

> Creator Desk URL Inspector is a paid API for AI agents from creator-desk-x402-isolated.onrender.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-13).

Inspects a public HTTPS URL and returns HTTP response metadata, page title, redirect chain, security headers, and a body fingerprint.

## Facts

- Endpoint: POST https://creator-desk-x402-isolated.onrender.com/v1/url/inspect?utm_source=zero.xyz
- Price: $0.005/call
- Payment: x402

- Tags: x402
- Canonical page: https://www.zero.xyz/c/creator-desk-url-inspector-61347390
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_a0fXecID-dAd_ui7CQHwj

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 creator-desk-url-inspector-61347390 -d '<json body>'
```

Example prompt: Can you inspect https://example.com for me — I want to see what HTTP status it returns, whether it redirects anywhere, what security headers it has, and what the page title is?

## When to prefer this

Use this endpoint when you need a lightweight, machine-payable (x402) way to inspect a single public URL's HTTP metadata, redirect behavior, security posture, and body fingerprint without running a full browser or scraping the DOM. It is ideal for agents that need to verify URL reachability, audit security headers, or trace redirects programmatically at low cost per call.

## Known failure modes

- Non-HTTPS or non-443 port URLs are rejected with an error
- Private/local IP destinations (e.g. localhost, 192.168.x.x) are rejected
- URL exceeds 2048 characters
- Target URL is unreachable or times out — latency_ms may be high and status absent
- Malformed URL fails schema validation before the request is made
- Payment of 0.005 USDC via x402 must succeed or the request is rejected with 402

## How this service works

Machine-callable x402-paid utilities for autonomous agents.

## Output

Returns a JSON object containing: HTTP status code, status text, latency in milliseconds, content type, content length, page title, canonical URL, final URL after redirects, the full redirect chain, a SHA-256 fingerprint of the response body with bytes read, a map of security header presence flags (CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy), a list of findings, the requested and inspected URLs, and a timestamp.
