## 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-bl-religion-belief-shelf-93de254e -d '<json body>'
```

Example prompt: Can you give me a list of up to 30 public-domain books on religion and religious experience from the ForgeMesh library — I'm especially interested in classic texts on the philosophy of religion and spirituality.

## When to prefer this

Use this endpoint when you need a curated, ranked list of public-domain books specifically in the religion, belief, or philosophy of religion domain (BL Library of Congress classification). Prefer it over full-text search when you want to browse the whole shelf rather than search by keyword, and over other shelves when the user's interest is specifically religious studies, spirituality, or philosophy of religion.

## Known failure modes

- limit exceeds 50 — API may cap or return an error
- no books match the shelf criteria — empty list returned
- x402 payment failure — call blocked if USDC payment is not properly handled
- network timeout or service unavailability
