## 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 forgemesh-library-pe-curated-shelf-53e0fd3f -d '<json body>'
```

Example prompt: Can you give me a list of up to 30 public-domain books from the PE shelf on ForgeMesh Library — things like classic dictionaries and English grammar texts?

## When to prefer this

Choose this endpoint when you need a curated, ranked list of public-domain books specifically in the PE subject category (English language, grammar, dictionaries, readers) and want drill-down routes for full-text access. Prefer this over full-text search when you want to browse the entire shelf rather than search for specific passages or keywords.

## Known failure modes

- Requesting a limit above 50 may be capped or rejected
- If the shelf has no results for the query parameters, an empty list is returned
- Payment failure (x402) if the 0.003 USDC transaction is not completed
- Network timeout if the service is temporarily unavailable
