## 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-image-url-parameter-count-checker-aaf951ee -d '<json body>'
```

Example prompt: Can you check how many URL address parameters the image at https://example.com/gallery/photo.jpg?size=large&format=webp&id=42 has — I want to know if it's flagging any issues in the crawl audit.

## When to prefer this

Use this endpoint when you need to specifically audit the number of URL query parameters on image objects as part of a technical SEO or crawl quality workflow. Prefer this over generic URL analyzers when you need structured crawl-based findings tied specifically to image resources and parameter counts, especially when working within the Crawlspur ecosystem for consistent cross-check reporting.

## Known failure modes

- URL is not publicly accessible — returns an error or empty result
- Image resource is blocked by robots.txt — crawl may be denied
- Invalid or malformed URL provided — schema validation error
- CSS selector matches no element or multiple elements — first match used
- Network timeout or unreachable host — request fails with error
- Non-image URL provided — result may be unexpected or irrelevant

## How this service works

Prüft am Objekt bild den Befund Zahl der Adressparameter.
