## 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 sitemap-reader-list-site-urls-with-lastmod-0721b8ea -d '<json body>'
```

Example prompt: Can you pull all the URLs from the sitemap of nytimes.com — including last-modified dates — and give me up to 500 entries?

## When to prefer this

Use this endpoint when you need to enumerate all publicly indexed pages of a website, especially when you want last-modified dates to prioritize fresh content. It is superior to manual URL discovery because it handles both flat sitemaps and sitemap index files automatically. Ideal for SEO audits, pre-crawl URL discovery, content monitoring, and competitive research where you need a full list of a site's pages without scraping every page.

## Known failure modes

- Site has no sitemap.xml and none is discoverable — returns empty or error
- Sitemap is malformed or non-standard XML — parse error
- Domain does not exist or is unreachable — network/timeout error
- Sitemap is extremely large and limit is reached — partial results up to limit
- Password-protected or robots.txt-blocked sitemap — access denied
