## 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 dracula-full-text-passage-retrieval-483a1065 -d '<json body>'
```

Example prompt: Search the actual text of Dracula for passages about what Van Helsing knows about vampires and give me up to 8 of the most relevant excerpts with their chapter locations.

## When to prefer this

Choose this endpoint when you need verbatim, cited passages from Dracula itself — not a paraphrase, summary, or AI-generated answer. Ideal for fact-checking literary claims, locating specific scenes, supporting academic or editorial work, or grounding an agent's response in primary-source text. Prefer over a general LLM answer when citation accuracy and source fidelity matter.

## Known failure modes

- Question too vague or off-topic returns low-relevance passages
- Limit parameter exceeding 15 is capped or rejected
- Missing question field returns a validation error
- Network or payment failure (x402) returns a 402 or 5xx error
- Very short questions may retrieve loosely related passages

## How this service works

Ask a question about Dracula 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 ranked list of up to 15 verbatim or near-verbatim text passages from Bram Stoker's Dracula that are most semantically relevant to the question, each annotated with its chapter number and location within the text. No AI-generated summary or paraphrase — raw source text only.
