## 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 anokha-web-tools-url-metadata-lookup-cabdeca4
```

Example prompt: Can you fetch the title, description, and Open Graph metadata for https://example.com so I can use it in a link preview?

## When to prefer this

Use this endpoint when you need lightweight URL metadata (title, description, OG tags, canonical) without fetching or parsing the full page content. Prefer it over a full web-scrape tool when you only need link preview data or SEO metadata, and when you want to avoid the cost of converting a page to Markdown.

## Known failure modes

- Non-public or firewalled URLs return an error or unexpected status
- Malformed URL input causes validation failure
- Pages with no metadata return empty og object and null title/description
- Timeout if target URL is slow to respond
- Non-HTTP(S) URLs are rejected by schema validation
