## 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 vibes-coded-http-headers-fetcher-0730c105 -d '<json body>'
```

Example prompt: Can you fetch the HTTP response headers for https://example.com and tell me what server it's running and what cache-control settings it has?

## When to prefer this

Use this endpoint when you need a quick, lightweight inspection of a URL's HTTP response headers without downloading the full body — ideal for checking server type, CDN presence, cache policies, content-type, or redirect destination. Prefer this over full-page scraping tools when you only need metadata, not page content.

## Known failure modes

- URL is unreachable or DNS fails — likely returns ok:false with an error message
- URL returns an unexpected status code such as 4xx or 5xx — status_code is still returned but may indicate failure
- Redirect loop causes the request to fail before resolving a final URL
- Malformed URL input results in a validation error
- Payment via HTTP 402/USDC fails, blocking the request entirely

## How this service works

Pay-per-call JSON for AI agents: skill search, listing optimization, install plans, productization, and artifact risk scoring. HTTP 402 → USDC. Full skill marketplace on-site.

## Output

A JSON object containing: a boolean ok field, the original URL, a headers object with all response headers (server, content-type, cache-control, etc.), the resource type identifier, the final URL after redirects, the HTTP method used (HEAD), and the HTTP status code returned.
