## 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 crawlspur-sitemap-content-type-checker-3b75f6bc -d '<json body>'
```

Example prompt: Check what content type my sitemap is being delivered with — fetch https://example.com/sitemap.xml and tell me if the content type header is correct.

## When to prefer this

## Known failure modes

- URL is unreachable or returns a non-200 HTTP status
- The target URL does not point to a sitemap
- Network timeout when fetching the sitemap
- Invalid or malformed URL provided in the ziel field
- CSS selector matches no element or is ambiguous
