## 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 x402helper-sitemap-fetcher-eb5b89fd
```

Example prompt: Can you fetch and parse the sitemap for https://example.com and give me a list of all the pages indexed there?

## When to prefer this

Use this endpoint when you need to programmatically discover all pages of a website via its sitemap, especially in an agent workflow that needs to enumerate site structure without full crawling. It is ideal when you have a root domain or direct sitemap URL and want structured URL extraction with minimal cost ($0.004 USDC per call). Prefer this over full web crawlers when sitemap coverage is sufficient and speed matters.

## Known failure modes

- Site has no sitemap.xml and root URL does not expose one — returns empty or error result
- Invalid or unreachable URL — network timeout or 404
- Sitemap is malformed XML — parse failure
- USDC payment rejected or insufficient — 402 Payment Required blocks the request
- URL points to a non-sitemap resource — unexpected content type

## How this service works

X402 micropayments server — AI agents pay USDC for OFAC screening, rates, and billing verification.

## Output

A JSON object containing parsed sitemap data including a list of URLs and associated metadata (e.g. last modified dates, priority, change frequency) extracted from the site's sitemap XML. Returns {success: true, result: {...}} on success.
