## 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-science-physics-shelf-55bf9cbb -d '<json body>'
```

Example prompt: Can you give me a list of the top 30 public-domain science and physics books available — I want titles I can drill into and read the full text?

## When to prefer this

Choose this endpoint when you need a curated, pre-ranked list of public-domain Science and Physics books specifically, rather than doing a full-text keyword search across the entire corpus. It is ideal for browsing or seeding a reading list without knowing specific titles in advance. Prefer it over the full-text search endpoint when the goal is discovery of titles rather than retrieval of specific passages.

## Known failure modes

- limit parameter exceeds 50 — likely returns an error or clamps to max
- limit set to 0 or negative integer — may return empty list or error
- Service temporarily unavailable — HTTP 5xx response
- Payment not completed via x402 protocol — request rejected before content is served
