## 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-don-quixote-passage-retrieval-53c3fc69 -d '<json body>'
```

Example prompt: Search Don Quixote for passages about why he attacks the windmills and return up to 8 relevant excerpts with their chapter citations.

## When to prefer this

Choose this endpoint when you need verbatim text retrieval from Don Quixote with precise citations — ideal for literary research, essay writing, quote verification, or any task requiring grounding in the actual source text rather than a paraphrased or AI-generated answer. Prefer this over a general LLM answer when you need citable, chapter-level provenance from the canonical text.

## Known failure modes

- Question is too vague or unrelated to the book's content, returning low-relevance passages
- Limit parameter exceeds 15, likely resulting in a validation error
- No passages found for highly specific or anachronistic queries
- Payment of $0.01 USDC not completed, resulting in 402 response blocking access

## How this service works

Ask a question about Don Quixote and get back the most relevant passages from the book itself, with chapter and location citations. Retrieval only — full-text search, not a generated summary or answer. No license, no API key required.

## Output

A list of up to 15 relevant passages (default 5) extracted directly from the full text of Don Quixote, each accompanied by a chapter reference and location citation within the book. No generated summaries — raw source text only.
