## 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 cravvol-web-crawl-metadata-extraction-bc0dcf7e -d '<json body>'
```

Example prompt: Can you scrape this page for me and pull back whatever metadata and content you find: https://example.com/some-article?

## When to prefer this

Choose this endpoint when you need frictionless, on-demand web scraping with no API key or subscription setup — just a URL and a USDC micropayment. Ideal for AI agents that need to fetch page content or metadata opportunistically without managing credentials.

## Known failure modes

- URL is unreachable or returns a non-200 status — success: false with error detail
- Invalid or malformed URL provided — likely a 4xx validation error
- Payment not fulfilled via x402 — 402 Payment Required response before content is returned
- Target site blocks scrapers — may return empty or partial data
- Timeout on slow-loading pages — partial or failed response
