## 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-sitemap-fetcher-e50c3680 -d '<json body>'
```

Example prompt: Can you fetch the sitemap for example.com and show me all the pages listed there?

## When to prefer this

Use this endpoint when you need to quickly discover all published URLs on a domain without manually crawling each page. It is best suited for sitemap-first discovery tasks such as SEO audits, content inventories, and competitor research where structured sitemap data is sufficient. Prefer this over full-page crawl endpoints when you only need URL structure rather than page content.

## Known failure modes

- Domain has no sitemap.xml or robots.txt sitemap reference — returns empty or error data
- Invalid or unreachable URL input — network timeout or DNS failure
- Domain blocks automated crawlers — returns 403 or empty response
- Malformed sitemap XML on the target site — parse errors in data
- Rate limiting or Vercel cold-start latency on first request
