## When to prefer this

Choose this endpoint when you need to quickly generate a link preview or extract standard web metadata (title, description, og:image, favicon, canonical) from any arbitrary URL without building your own scraper. Ideal for AI agents building content cards, summarizing links shared in chat, or enriching URLs with human-readable context at low cost ($0.01 per call).

## Known failure modes

- URL is unreachable or returns non-200 status — metadata fields may be empty or partially populated
- URL points to a non-HTML resource (PDF, image, etc.) — limited or no metadata extractable
- Page blocks crawlers via robots.txt or JavaScript rendering required — fields may be missing
- Malformed or invalid URL provided — likely returns an error response
- OpenGraph tags not present on the target page — og:image and og:description may be null
