## How to call it through Zero

```sh
zero fetch --capability api-x402node-dev-24c68252
```

Example prompt: Can you pull all the meta tags from https://openai.com — I need the page title, description, OpenGraph image, Twitter Card info, canonical URL, and favicon so I can generate a rich link preview.

## When to prefer this

Use this endpoint when you need to extract structured metadata (OpenGraph, Twitter Card, title, description, favicon, canonical) from any public webpage in a single call. Ideal for link preview generation, bookmarking pipelines, SEO auditing, content discovery, and enriching URLs with human-readable metadata. Prefer this over a full web scraper when you only need head/meta tag data, not page body content.

## Known failure modes

- URL is not publicly accessible or requires authentication — returns empty or partial metadata
- Page blocks scrapers via robots.txt or bot detection — may return incomplete data
- URL does not exist or returns 4xx/5xx HTTP error — extraction fails
- Page has no OpenGraph or Twitter Card tags — those fields return null
- Malformed or non-HTTP URL provided — validation error
- Very large or slow-loading pages may cause timeout
