Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```

Example prompt: Show me up to 30 public-domain books from the BF occult and parapsychology shelf — I'm interested in grimoires, demonology, and spirit-invocation texts like the Lesser Key of Solomon.

## When to prefer this

Choose this endpoint when you specifically want a curated, ranked list of public-domain books in the BF Library of Congress classification (psychology, parapsychology, occultism, demonology, witchcraft). Prefer it over full-text search when you want a broad shelf browse rather than passage-level retrieval, and over general web search when you need verified public-domain texts with drill-down full-text access.

## Known failure modes

- Limit exceeds 50 — request capped or rejected
- Network/payment failure via x402 protocol — no results returned
- Empty shelf if BF index is temporarily unavailable
