## When to prefer this

Use this endpoint when you need a direct, ready-to-use EPUB download link for a specific book and want to skip the intermediate search step. Best when you already know the book title and/or author. If you need to first discover book metadata or browse multiple editions, use the sibling search endpoint first, then pass the resulting URL to this endpoint.

## Known failure modes

- Book not found in Anna's Archive — no matching result returned
- Ambiguous title with multiple authors — wrong edition returned
- EPUB version unavailable for requested book — only other formats exist
- Network timeout reaching Anna's Archive — service unavailable error
- Invalid or missing book identifier in request — 400 bad request
