## When to prefer this

Use this endpoint when you need lightweight, structured metadata about a web page without doing full content extraction or AI analysis. Ideal for populating article cards, link previews, content indexing pipelines, or any workflow that needs publication date, author, og: tags, or reading time from a URL with a single call and no scraping infrastructure.

## Known failure modes

- URL is unreachable or returns a non-200 status — metadata fields will be missing or empty
- Page has no meta tags or Open Graph tags — response returns null values for those fields
- URL points to a non-HTML resource (PDF, image) — extraction may fail or return partial data
- Paywalled or bot-blocked pages may return incomplete metadata
- Malformed URL input results in a 400 error
