Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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-curated-shelf-q-74af5387 -d '<json body>'
```

Example prompt: Show me up to 30 public-domain books from the Q shelf on the Forgemesh library — I'm interested in popular science and nature study titles.

## When to prefer this

Choose this endpoint when you need to browse or enumerate the curated Q-subject public-domain book collection on Forgemesh, particularly for science, natural history, or education texts. Prefer the full-text search endpoint instead if you need keyword or semantic search across all books; use this when you want a ranked shelf listing for the Q category specifically.

## Known failure modes

- limit exceeds maximum of 50 — clamp or return error
- empty result if shelf has no matching entries
- payment failure via x402 protocol if USDC balance is insufficient
- network timeout on the POST request
