## 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-parameter-url-adressparameter-z-hler-ddad6700 -d '<json body>'
```

Example prompt: Can you check how many URL query parameters the page at https://example.com/shop?category=shoes&color=red&size=42&sort=asc has, so I can audit it for SEO crawlability?

## When to prefer this

Use this endpoint when you need a precise, automated count of query parameters on a specific URL as part of a technical SEO or crawlability audit pipeline. Prefer it over manual inspection when processing multiple URLs programmatically or when integrating parameter-count checks into a monitoring workflow. It is specifically designed for the parameter-url object type within the Crawlspur audit framework.

## Known failure modes

- Invalid or non-public URL returns an error or empty result
- URL not reachable or returning non-2xx HTTP status causes fetch failure
- Malformed input schema (missing or too-long ziel field) returns validation error
- Private/internal IP addresses or localhost URLs rejected
- CSS selector matches no element, falls back to first match or returns error
