## 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-robots-txt-sitemap-inclusion-check-e22985d5 -d '<json body>'
```

Example prompt: Check whether the robots.txt file for https://example.com is included in the site's XML sitemap.

## When to prefer this

Use this endpoint when you specifically need to check whether a domain's robots.txt file is referenced or included in its XML sitemap — a technical SEO compliance check. Prefer this over generic site auditing tools when you need a precise, single-signal check on robots.txt sitemap presence rather than a full crawl or broad audit.

## Known failure modes

- Target URL is unreachable or returns a non-2xx HTTP status
- robots.txt file not found at the expected path
- Sitemap is missing or malformed
- Invalid URL format provided in the 'ziel' field
- Domain does not have a publicly accessible sitemap
- Rate limiting or access restrictions on the target domain
