## 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 vextorium-sitemap-url-extractor-1475b12c -d '<json body>'
```

Example prompt: Can you pull all the URLs from example.com's sitemap, filtering for only pages that contain 'blog' in the URL, and limit the results to 500?

## When to prefer this

Use this endpoint when you need to programmatically discover all publicly indexed pages of a website without manual sitemap navigation. It is particularly valuable when the sitemap is nested in a sitemap index, compressed as .gz, or not directly linked — since it auto-discovers via robots.txt. Prefer it over general web scrapers when you specifically need structured sitemap data with last-modified timestamps for SEO auditing, change monitoring, or building a page inventory.

## Known failure modes

- Site has no sitemap.xml and robots.txt provides no sitemap directive — returns empty or error
- Sitemap is malformed XML — parsing may fail or return partial results
- Site blocks the crawler (403/429) — returns error or no URLs
- .gz sitemap files that cannot be decompressed — may be skipped
- URL limit exceeded silently — returns up to the specified limit without warning
- Filter text returns zero matches — empty URL array returned

## How this service works

List the URLs of a site's XML sitemap (found via robots.txt if needed, following sitemap indexes and .gz files) with last-modified dates, optionally filtered by text. Discover a site's pages for crawling or monitoring.

## Output

A JSON object containing an array of URLs with their last-modified dates and priority values, the most recently modified date across all URLs, the total number of URLs returned, and a list of sitemap files that were read during discovery.
