## When to prefer this

Use this endpoint when you need a direct EPUB download URL for a specific book and have the title and/or author. Prefer this over search-only endpoints when the goal is to actually obtain the file, not just find metadata. Best suited when the user wants to read or process the full text of a book.

## Known failure modes

- Book not found in archive — no matching result returned
- Ambiguous title/author — wrong book resolved
- Download link expired or invalid — URL returned but file unavailable
