## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

## When to prefer this

Use this endpoint when you need a single, ready-to-use EPUB download URL for a specific book title in one step, without needing to manually parse search results or resolve intermediate page URLs. Prefer this over sibling endpoints when you want a fully automated end-to-end lookup rather than a two-step search-then-resolve flow.

## Known failure modes

- Ambiguous title matches multiple books — may return incorrect result
