## 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 api-x402node-dev-15c8ff68
```

Example prompt: Can you pull the OpenGraph metadata from https://openai.com/blog/chatgpt — I need the og:title, og:image, og:description, and canonical URL so I can build a link preview card for it.

## When to prefer this

Use this endpoint when an AI agent needs to generate a rich link preview, understand the content of a URL without full-page scraping, or perform content moderation checks based on social metadata. Prefer it over full HTML scrapers when only OG/Twitter Card metadata is needed — it's cheaper, faster, and purpose-built for preview generation.

## Known failure modes

- Target URL is unreachable or returns non-200 status — scrape fails
- Page has no OpenGraph tags — fields return null or empty
- URL is behind a login wall or bot protection — extraction blocked
- Malformed URL input — validation error returned
- Rate limiting or timeout on the target server — partial or no data

## How this service works

Extract OpenGraph (og:title, og:image, og:description, og:type) + Twitter Card meta + basic <title>/<meta>/canonical from any URL. Built for AI agents generating shareable previews, understanding link content, and content moderation. Use url param Accepts payment on Base or Solana — either network works.

## Output

Returns structured OpenGraph fields (og:title, og:image, og:description, og:type), Twitter Card meta tags, the page's HTML <title>, meta description, and canonical URL extracted from the target page.
