## 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 agentservices-url-metadata-extraction-43d7b109
```

Example prompt: Can you fetch the metadata and link preview info for this URL: https://example.com/article/some-news-story?

## When to prefer this

Use this endpoint when you need to quickly extract structured metadata (title, description, Open Graph tags) from a single URL without crawling the full page content. Ideal for link enrichment, preview generation, or populating catalog fields from URLs. Prefer this over a full web scraper when you only need head-level metadata, not body content.

## Known failure modes

- URL is unreachable or returns a non-200 status — metadata not available
- Target page blocks bots/crawlers — returns empty or incomplete metadata
- URL is malformed or missing — request validation error
- Page has no metadata tags — returns minimal or empty fields
- Timeout on slow-loading pages — partial or no result
