## 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 avedaris-page-metadata-fetcher-f53d7329 -d '<json body>'
```

Example prompt: Can you look up the title, description, and final URL for https://openai.com/research/gpt-4 and tell me what the page is about?

## When to prefer this

Use this endpoint when you need lightweight, structured page metadata (title, description, canonical URL, redirect resolution) without full HTML scraping or content parsing. It is ideal for building link previews, verifying redirect chains, or enriching URLs with human-readable summaries at low cost ($0.003/call). Prefer this over full scraping endpoints when you only need head-level metadata rather than body content.

## Known failure modes

- URL is unreachable or returns a non-200 status (status field reflects actual HTTP code)
- Page has no meta description or canonical tag (those fields return null)
- URL redirects to a page that blocks bots (may return empty or partial metadata)
- Malformed or too-short URL triggers input validation error
- Timeout if the target page is slow to respond

## How this service works

## Output
