## 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-technical-indexability-check-eeac82e7 -d '<json body>'
```

Example prompt: Check if the product image at https://example.com/products/widget.jpg is technically indexable by search engines — use the CSS selector #main-product-image if you need to target the specific element on the page.

## When to prefer this

Use this endpoint when you specifically need to check the technical indexability of an image element on a webpage, as opposed to checking general page indexability, meta-robots values, or sitemap presence. It is ideal for targeted image SEO audits, diagnosing why a specific image is not appearing in Google Image Search, or validating image crawl settings before a site launch. Choose this over the sibling Meta-Robots endpoint when you need a holistic technical indexability verdict rather than just the meta-robots directive value.

## Known failure modes

- Image URL is not publicly accessible — endpoint may return an error or non-indexable status
- CSS selector matches no element or multiple elements — first matching element is used
- URL exceeds 2048 character limit — request rejected
- Invalid user_agent pattern — request rejected with validation error
- Target server blocks the crawl request — may result in inconclusive finding
- Malformed or private URL provided — error returned
