## 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 meta-tag-description-2d80cfd3
```

Example prompt: Check the meta description tag on https://example.com — tell me if it's present, what it says, how long it is, and whether there are any issues like it being empty, a placeholder, or too long.

## When to prefer this

Use this endpoint when you need a fast, focused, single-tag check on a page's description meta tag for SEO auditing or social-preview validation. It is purpose-built for exactly one tag and returns a clean quality verdict, making it preferable over full-page scrapers or general HTML parsers when you only care about the description meta tag presence and quality.

## Known failure modes

- Page URL not provided or not resolvable — returns error indicating the target page could not be fetched
- Page has no description meta tag — returns presence=false with no content
- Network timeout fetching the target page — returns a timeout or fetch error
- Meta description value is dynamically injected via JavaScript and not present in static HTML — may return absent even if visible in browser
- Invalid HTTP method used — endpoint only accepts GET

## How this service works

The description 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 description meta tag is present on the page, its full text content (from either name='description' or property='og:description' form), the character length of that content, and a diagnostic note flagging issues such as the tag being absent, empty, containing a placeholder value, or exceeding recommended length limits.
