Example prompt: Can you pull the page title, meta description, canonical URL, and Open Graph metadata from https://example.com/blog/my-article so I can build a link preview?

## When to prefer this

Choose this endpoint when you need structured web page metadata (title, description, OG tags, Twitter cards) for link previews, SEO audits, or content verification without running a full browser or headless Chrome. It is lightweight, fast, and priced at $0.002 USDC per call via x402, making it suitable for high-volume metadata lookups on public pages.

## Known failure modes

- URL is not publicly accessible or returns a non-2xx HTTP status
- Page has no meta tags or minimal HTML (e.g. behind a login wall)
- URL is malformed or not a valid HTTP/HTTPS address
- Page uses heavy JavaScript rendering so static metadata is absent
- Request times out due to slow target server
- Payment of $0.002 USDC via x402 on Base fails or is not included
