## 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-video-content-type-checker-ac094298 -d '<json body>'
```

Example prompt: Can you check what content type is actually being delivered when crawlers hit this video URL — https://example.com/videos/intro.mp4 — and tell me if it matches what a video should return?

## When to prefer this

Use this endpoint when you specifically need to verify the HTTP content type header delivered for a video resource — particularly for technical SEO audits, pre-launch checks, or debugging video indexing issues. It is purpose-built for video objects within the Crawlspur SEO inspection suite, making it more precise than a generic HTTP header checker when video MIME type compliance is the specific concern.

## Known failure modes

- URL is not publicly accessible — returns error or no finding
- Video resource returns a non-video content type (e.g. text/html redirect page)
- URL exceeds 2048 character limit
- Network timeout fetching the target URL
- CSS selector matches no element if object-based input is used
- Invalid user agent string format rejected by schema pattern

## How this service works

Prüft am Objekt video den Befund ausgelieferten Inhaltstyp.

## Output

Returns a finding (Befund) describing the detected content type of the video resource at the given URL, including the actual MIME type delivered in the HTTP response, allowing verification that the video is served correctly for crawler consumption.
