## 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 arch-tools-extract-metadata-3bb78fa4 -d '<json body>'
```

Example prompt: Can you extract the metadata from this URL — https://example.com/article/some-post — I need the title, description, author, and any tags or publish date it has?

## When to prefer this

Choose this endpoint when you need structured metadata fields (title, description, author, dates, tags) extracted from a URL or text without performing a full page crawl or content extraction. It is particularly useful for cataloging, SEO analysis, link previews, or enriching records with page-level metadata. Prefer it over extract-page when you only need metadata rather than full page content, and over extract-entities when you want document-level metadata rather than named entities within the body text.

## Known failure modes

- URL is unreachable or returns non-200 status — metadata may be partial or absent
- Paywalled or JavaScript-rendered pages may yield incomplete metadata
- Raw text with no recognizable metadata structure returns minimal fields
- Malformed URL input returns a validation error
- Payment failure or insufficient USDC balance prevents the call from completing
