## 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-eb4c4f4f -d '<json body>'
```

Example prompt: Can you check whether my sitemap at https://example.com/sitemap.xml is returning the correct HTTP 200 status, or if it's throwing an error like 404 or 500?

## When to prefer this

Use this endpoint when you need to programmatically verify whether a sitemap URL responds with the correct HTTP status code, especially as part of a technical SEO audit, post-deployment check, or monitoring workflow. It is specifically designed for sitemap objects rather than generic URL status checks, making it more appropriate than a general HTTP ping tool when the context is SEO crawlability.

## Known failure modes

- Invalid or malformed URL returns a validation error
- Unreachable host or DNS failure results in a connection error finding
- Sitemap behind authentication returns 401 or 403, which the tool reports but cannot bypass
- Timeouts on slow servers may result in incomplete findings
- URL longer than 2048 characters is rejected by schema validation

## How this service works

Prüft am Objekt sitemap den Befund HTTP-Status der Sitemap.

## Output

Returns the HTTP status code observed when fetching the target sitemap URL, along with the crawl finding indicating whether the sitemap is accessible, redirecting, or returning an error. This lets agents and users determine if the sitemap is correctly served for search engine indexing.
