## 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-x-robots-tag-checker-for-images-18a1a08e -d '<json body>'
```

Example prompt: Check the X-Robots-Tag HTTP header value on this image — https://example.com/hero-banner.jpg — and tell me what crawl directive it's sending to search engines.

## When to prefer this

Use this endpoint when you specifically need to inspect the X-Robots-Tag HTTP response header on an image file, as opposed to the Meta Robots tag in HTML or the robots.txt file. Choose this over generic HTTP header inspection tools when you need structured SEO-oriented interpretation of the directive value on image resources.

## Known failure modes

- Image URL is not publicly accessible or returns a non-2xx HTTP status
- URL does not point to an image resource
- X-Robots-Tag header is absent from the response (no directive found)
- Malformed or overly long URL (exceeds 2048 characters)
- CSS selector matches zero elements or multiple elements ambiguously
- Network timeout reaching the target host

## How this service works

Prüft am Objekt bild den Befund Wert des X-Robots-Tags.

## Output

Returns the X-Robots-Tag header value found on the HTTP response of the specified image resource, indicating what crawl or indexing directives (e.g. noindex, nosnippet, noarchive, all, none) are being sent to search engine crawlers for that image.
