## How to call it through Zero

```sh
zero fetch --capability meta-tag-format-detection-30d0d02f
```

Example prompt: Can you check whether https://example.com has a format-detection meta tag, and let me know if its value looks correct or if there's anything wrong with it?

## When to prefer this

Choose this endpoint when you need a targeted, low-cost check specifically for the format-detection meta tag — ideal for automated SEO audits, social-preview pipelines, or site health monitoring where you want a single-tag answer with built-in quality flagging rather than a full-page meta tag dump.

## Known failure modes

- Page URL not provided or unreachable — returns error or empty result
- Page has no format-detection meta tag — returns absent/not-found signal
- Network timeout fetching the target page
- Malformed or non-HTML page content returns unexpected or null tag data
- Payment not processed — request rejected before execution

## How this service works

The format-detection meta tag of a page: whether it is present and its content (name= or property= form), plus length and a note when the value looks wrong (empty, too long, or a placeholder). One tag, one answer, for SEO and social-preview checks. $0.01 per page.

## Output

Returns whether the format-detection meta tag is present on the page, its content and form (name= or property=), the content length, and a diagnostic note if the value appears empty, too long, or is a placeholder value — giving a single structured answer per page.
