## 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 agent402-tools-page-metadata-fetcher-28e06eb9
```

Example prompt: Can you fetch the page metadata for https://openai.com — I need the title, description, OpenGraph tags, and favicon URL?

## When to prefer this

Use this endpoint when you need to quickly extract structured metadata (title, description, OG tags, Twitter cards, canonical, favicon) from a single public URL without running a full browser render. Ideal for link preview generation, SEO auditing, social share validation, or content enrichment pipelines. Choose a screenshot endpoint instead if you need visual rendering.

## Known failure modes

- URL is not publicly accessible or requires authentication — may return empty or partial metadata
- Non-HTML resources (PDFs, images) may lack most metadata fields
- Pages with JavaScript-rendered metadata may not be fully captured
- Network timeout if the target page is slow to respond
- Invalid or malformed URL input returns an error

## How this service works

Fetch page metadata for a URL: title, description, OpenGraph, Twitter cards, canonical URL, favicon.

## Output

Returns structured metadata extracted from the target URL including: page title, meta description, OpenGraph properties (og:title, og:description, og:image, etc.), Twitter card tags, the canonical URL, and the favicon URL.
