## 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 cerwal-web-crawler-c1724df6 -d '<json body>'
```

Example prompt: Can you crawl https://example.com for me and pull back the content from up to 5 pages starting from the homepage?

## When to prefer this

Choose this endpoint when you need pay-per-use web crawling with no subscription or API key setup, especially in agentic pipelines where USDC micropayments via x402 are acceptable. Ideal for one-off or infrequent scraping tasks where provisioning a full scraping service is overkill.

## Known failure modes

- URL is unreachable or returns a non-200 status — crawl may return success: false
- maxPages not specified — defaults to a single page or service default
- Target site blocks crawlers via robots.txt or bot detection — partial or empty data returned
- Invalid or malformed URL input — request rejected
- Payment failure via x402 — request not processed
