## 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 metalift-sitemap-fetcher-b4ed6434 -d '<json body>'
```

Example prompt: Fetch all the URLs listed in the sitemap for https://www.example.com so I can batch-scrape every page on the site.

## When to prefer this

Use this endpoint when you need a complete, structured list of all URLs on a site before performing batch scraping. It is preferable to the single-page link-discovery (map) endpoint when you want site-wide coverage rather than just links from one HTML page. It is more efficient than crawling page-by-page when the site has an XML sitemap.

## Known failure modes

- Site has no sitemap.xml and robots.txt provides no sitemap directive — returns empty or error
- URL provided is not a valid homepage or sitemap URL — validation error
- Target site blocks automated requests to sitemap — access denied or timeout
- Malformed XML sitemap — parsing failure
- Network timeout reaching the target domain

## How this service works

Metalift sitemap: fetch URLs from XML sitemaps (robots.txt or /sitemap.xml). Prefer over map for site-wide URL lists before batch scrape. (1 credit ≈ $0.002 USDC)

## Output

A list of URLs extracted from the site's XML sitemap(s), discovered via robots.txt or /sitemap.xml, ready for use in batch scraping or further processing.
