## 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 forgemesh-library-book-chapter-retrieval-5f326705 -d '<json body>'
```

Example prompt: Can you fetch chapter 4 of Moby Dick — that's Gutenberg book ID 2701 — so I can read it?

## When to prefer this

Use this endpoint when you need the full text of a specific chapter from a public-domain Gutenberg book and already know (or can look up) the book_id and valid chapter range. It is ideal for sequential reading, chapter-by-chapter analysis, or extracting a targeted portion of a long work. Prefer /book-metadata first to discover valid chapter numbers. Use the full-text search sibling endpoint instead if you want passages matching a query rather than a specific numbered chapter.

## Known failure modes

- Invalid book_id returns an error — use /book-metadata first to confirm the book exists
- Chapter number out of valid range returns an error — use /book-metadata to check chapter_range before calling
- Chapter 0 may be empty or minimal if no front matter exists before the first heading
- Network or service errors may return HTTP 5xx responses
- Payment failure via x402 protocol may block access if USDC balance is insufficient

## How this service works

Retrieve the full text of one chapter from an indexed book by book_id and chapter number. Chapter 0 is front matter before the first detected heading. Use /book-metadata first to see a book's valid chapter range. No license, no API key required.

## Output

The full plain text of the requested chapter from the specified Gutenberg book, enabling reading, analysis, or further processing of public-domain literary content.
