## 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-art-history-architecture-shelf-n-695d5ba1 -d '<json body>'
```

Example prompt: Can you show me up to 30 public-domain books on art history, painting, sculpture, and architecture from library.forgemesh.io's curated shelf?

## When to prefer this

Choose this endpoint when you need a curated, pre-ranked list of public-domain art history, painting, sculpture, or architecture texts rather than doing a free-text search across the whole corpus. It is ideal for browsing or building reading lists in the art history domain without needing a search query. Use the full-text search sibling endpoint if you need keyword or semantic search across all subjects.

## Known failure modes

- limit exceeds 50 — server may reject or cap the response
- no books match the shelf criteria — empty list returned
- payment of $0.003 USDC not fulfilled — 402 error blocking access
- network timeout if the corpus index is temporarily unavailable
