## 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
zero fetch --capability library-forgemesh-io-public-domain-book-index-catalog-c3676c1c -d '<json body>'
```

Example prompt: Show me all the indexed public-domain books available in the library — give me up to 50 results with links so I can drill down into any of them.

## When to prefer this

Use this endpoint when you need to enumerate or browse the full catalog of indexed public-domain books before deciding which title to retrieve or search. Prefer this over full-text search when you want a directory/catalog view rather than passage-level results, or when you need to discover what books are available before querying them individually.

## Known failure modes

- Limit exceeds max of 50 — likely clamped or error returned
- No results if index is empty or service is unavailable
- Payment failure if x402 USDC payment is not processed correctly
- Network timeout if the endpoint is temporarily unavailable

## How this service works

Curated shelf: Indexes — 230 public-domain books including The Works of Edgar Allan Poe, The Raven Edition Table Of Contents And Index Of The Five Volumes, The History of the Decline and Fall of the Roman Empire Table of Contents with links in the HTML file to the two Project Gutenberg editions (12 volumes). Returns a ranked list with drill-down routes for full-text retrieval. No license, no API key required.

## Output

A ranked list of up to 230 public-domain book entries, each with title, author, and drill-down routes that point to full-text retrieval endpoints. Pagination is controlled by the 'limit' parameter (default 20, max 50).
