## 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 agent-utility-network-page-metadata-extractor-d509bbb6 -d '<json body>'
```

Example prompt: Can you grab the page title, description, and canonical URL for https://openai.com/ so I can build a link preview card?

## When to prefer this

Use this endpoint when you need lightweight, structured metadata about a webpage — especially page title, description, canonical URL, and redirect resolution — without needing full HTML content or deep scraping. It is ideal for building link previews, verifying SEO tags, or resolving redirect chains cheaply at $0.005 per call via x402/Base USDC.

## Known failure modes

- URL is unreachable or returns a non-200 status — status field reflects the actual HTTP code returned
- URL resolves to a page with no meta description or canonical tag — those fields return null
- Malformed or too-short URL (< 8 chars) — request validation error
- URL exceeds 8192 character limit — rejected by schema validation
- Target page requires JavaScript rendering — metadata may be incomplete or missing since only static HTML is parsed
