## 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`):

Example prompt: Can you check whether https://example.com/blog/my-article is technically indexable by search engines based on its URL rules?

## When to prefer this

Use this endpoint when you need to specifically audit a URL's technical indexability from a URL-rule perspective (e.g. URL patterns, parameter handling) as part of a technical SEO workflow. It is part of a broader crawlspur suite of SEO checks — prefer this over generic HTTP checkers when the concern is search engine indexability via URL-level rules specifically.

## Known failure modes

- Invalid or unreachable URL returns an error or empty finding
- URL longer than 2048 characters is rejected
- Non-public or private IP addresses may be rejected
- Malformed input object missing required 'adresse' field causes validation error
- Network timeout if the target URL is slow to respond
