## 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-page-technical-indexability-check-05540ea3 -d '<json body>'
```

Example prompt: Can you check whether https://example.com/my-landing-page is technically indexable by search engines — I want to know if anything is blocking it from being crawled or indexed?

## When to prefer this

Use this endpoint when you need to audit a specific page's technical indexability status for SEO purposes, especially when diagnosing why a page may not appear in search engine results. Prefer it over general crawl tools when you need a focused, per-page indexability verdict rather than a full-site crawl.

## Known failure modes

- Invalid or non-public URL returns an error or empty result
- URL is unreachable or returns a non-200 HTTP status, leading to an error finding
- Malformed input schema (missing 'ziel' field) causes a 400-type validation error
- URL behind authentication or firewall cannot be fetched, resulting in an access error
- CSS selector matches no element, falling back to first match or returning partial result
