## 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-book-quotes-3f933d40 -d '<json body>'
```

Example prompt: Pull up to 10 notable passages from Crime and Punishment (Gutenberg book ID 2554) that relate to the theme of guilt.

## When to prefer this

Use this endpoint when you need real verbatim passages from a specific known Gutenberg book and optionally want to filter by a theme or keyword within that book. Prefer this over the full-corpus search endpoint when you already know the exact book_id and want targeted in-book retrieval rather than cross-book search.

## Known failure modes

- Invalid or unindexed book_id returns no results or an error
- Theme keyword yields no matching passages within the specified book
- Limit exceeding max of 20 may be clamped or rejected
- Payment of 0.005 USDC not fulfilled results in 402 response

## How this service works

Get notable passages from one indexed book by book_id. Pass an optional theme to full-text search within that book, or omit it for a sample of short dialogue-bearing passages. Returns real excerpts, never generated or paraphrased. No license, no API key required.

## Output

Returns a list of real verbatim excerpts from the specified Gutenberg book — never AI-generated or paraphrased. Each passage is a notable or dialogue-bearing segment from the original text. When a theme is provided, results are filtered by full-text search within the book; otherwise a representative sample is returned.
