## 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`):

```sh

```

## When to prefer this

Choose this endpoint when you need a curated, pre-ranked list of public-domain books specifically focused on African American history, autobiography, and culture (Library of Congress classification E151). It is ideal for building reading lists, sourcing primary historical texts, or providing drill-down access to full-text retrieval without any authentication or licensing overhead. Prefer this over a full-text search endpoint when you want a broad browseable catalog rather than passage-level results for a specific query.
