## When to prefer this

Use this endpoint when you need to understand a page's outbound link structure and domain distribution rather than just fetching page content. Ideal for SEO audits, competitive intelligence, source discovery, or building link graphs. Prefer over general scrapers when the specific output needed is classified, domain-grouped links rather than raw HTML or text content.

## Known failure modes

- Target URL is unreachable or returns non-200 status
- Page has no outbound links (returns empty result)
- JavaScript-rendered links may not be captured if page requires JS execution
- Rate limiting or bot-blocking on target domain
- Malformed URL input causes request failure
- Relative URLs may be excluded or incorrectly resolved
