Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-url-regel-sitemap-http-status-checker-3a8a598d -d '<json body>'
```

Example prompt: Check the HTTP status that crawlspur.halowerk.com gets back when it probes the sitemap URL rule at https://example.com/sitemap.xml — I want to know if that URL is returning a valid 200 response or something broken.

## When to prefer this

Use this endpoint when you need to specifically audit the HTTP status code of a URL rule as it appears in a sitemap context, particularly for technical SEO diagnostics. Prefer this over generic HTTP checkers when you want crawlspur's structured SEO-focused finding format and are already auditing sitemap objects.

## Known failure modes

- Target URL is unreachable or times out — returns an error or non-200 finding
- Invalid or malformed URL provided — schema validation error
- URL rule is behind authentication and returns 401 or 403
- CSS selector matches no element — falls back to first match or returns empty finding
- Network-level block prevents the probe from completing

## How this service works

Prüft am Objekt url-regel den Befund HTTP-Status der Sitemap.

## Output

Returns the HTTP status finding for the specified URL rule object as evaluated in the context of sitemap crawling — typically indicating whether the URL responds with a success code (e.g. 200), a redirect (3xx), a client error (4xx), or a server error (5xx).
