## 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-http-status-checker-parameter-url-81f6f556 -d '<json body>'
```

Example prompt: Can you check the HTTP status of the sitemap associated with this URL — https://example.com/page?category=shoes — and tell me if it's returning 200 or throwing an error?

## When to prefer this

Choose this endpoint when you need to specifically audit the HTTP status of a sitemap as seen from a parameterized URL context, particularly during technical SEO audits of parameter-driven pages. It is distinct from robots-file-based sitemap checks and is best used when diagnosing indexability issues for URLs with query parameters.

## Known failure modes

- Invalid or unreachable target URL returns an error finding
- Non-public or firewall-blocked URLs may result in connection failures
- Malformed URL input rejected by schema validation (minLength/maxLength constraints)
- Sitemap not found at expected location returns a 404 finding
- Target server rate-limiting may cause intermittent failures

## How this service works

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

## Output

Returns the HTTP status finding for the sitemap associated with the given parameterized URL, indicating whether the sitemap is reachable (e.g. 200 OK) or returning an error status (e.g. 404, 500), as part of a structured crawl audit result.
