## 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-pq-shelf-b98a1f04 -d '<json body>'

Example prompt: Can you show me a list of classic public-domain books from the PQ literary shelf — things like The Count of Monte Cristo or Arsène Lupin — and give me up to 30 results?

## When to prefer this

Choose this endpoint when you need a curated, ranked catalog of public-domain books specifically from the PQ literary classification (primarily French and European fiction, adventure, and detective novels). It is ideal for browsing or seeding a reading list when you know you want classic works like The Count of Monte Cristo, Carmen, or Arsène Lupin. For full-text search across the entire corpus, use the full-text search sibling endpoint instead.

## Known failure modes

- Exceeding the max limit of 50 returns an error or is clamped
- Payment failure via x402 protocol returns a 402 status before results are delivered
- Empty or malformed request body may return default 20 results or an error
- If the shelf index is temporarily unavailable, the endpoint may return a 503 or timeout
