## 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-architecture-shelf-330f6beb -d '<json body>'
```

Example prompt: Can you pull up the curated list of public-domain architecture books — give me the top 30 results with links so I can drill into the full texts?

## When to prefer this

Choose this endpoint when you need a curated, ranked list of public-domain architecture and art-criticism books — particularly Victorian-era and classical texts — without requiring an API key or license. Prefer it over general full-text search when you want a shelf-level browse rather than passage-level retrieval, and when cost per call ($0.003 USDC) is acceptable for structured discovery of up to 50 canonical works.

## Known failure modes

- Limit parameter exceeds 50 — likely clamped or rejected
- Network timeout if the corpus index is unavailable
- Empty result set if the shelf has no books matching internal ranking criteria
- Payment failure (x402) if USDC balance is insufficient
