## When to prefer this

Use this endpoint when you have a specific article or blog post URL and need to find the author's email for outreach, collaboration, licensing, or PR purposes. Prefer this over generic email-finding tools when you are starting from a content URL rather than a person's name or company domain.

## Known failure modes

- Article URL not indexed or author metadata not available — returns empty result
- Invalid or malformed URL input — returns error
- Author email not publicly discoverable — returns no results
- Paywalled or JavaScript-rendered pages may not be parseable
- Rate limiting or payment failure at $0.01 per call
