answers 402

Get structured metadata for any public web page in one call: title, meta description, canonical URL, Open Graph and Twitter card tags, favicons, JSON-LD schema types, language and the heading outline. Use it to build link previews and social cards, classify or dedupe URLs, and run SEO and AI-readability audits - far cheaper than fetching and parsing the whole page.

We sent a real GET request to this endpoint and it answered 402 with payment requirements we could parse.
