## 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-philosophy-shelf-e4792d31 -d '<json body>'
```

Example prompt: Can you pull up the top 10 most historically popular public-domain philosophy and ethics books available — I want titles, authors, and years so I can pick something to read?

## When to prefer this

Use this endpoint when you need a pre-curated, popularity-ranked catalog of public-domain philosophy and ethics texts — specifically ancient to early-modern thought — and want structured metadata (title, author, year, book_id) to drive further full-text retrieval. Prefer this over a full-text search endpoint when you want to browse or present a shelf rather than find specific passages.

## Known failure modes

- limit exceeds 50 — API may reject or cap silently
- invalid limit type (non-integer) returns validation error
- empty result if index is temporarily unavailable
- network/payment failure due to x402 micropayment issues
