## 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-music-shelf-6efa3fbf -d '<json body>'
```

Example prompt: Show me up to 30 public-domain music books from the ForgeMesh library shelf — things like music history, composer biographies, folk songs, or ballads.

## When to prefer this

Choose this endpoint when you need a curated, pre-filtered list of public-domain books specifically in the music category, rather than running a full-text keyword search across the entire corpus. Ideal for browsing or discovery use cases where the user wants to explore music literature without a specific query string.

## Known failure modes

- limit exceeds 50 — likely clamped or returns an error
- payment of $0.003 USDC not provided — 402 Payment Required response
- network timeout if the corpus index is temporarily unavailable
- empty result if the shelf index is misconfigured

## How this service works

Curated reading list on Music for tutoring agents, quiz generators, and reading apps — 494 public-domain books (e.g. My Life — Volume 1, The Letters of Wolfgang Amadeus Mozart — Volume 01, Cowboy songs, and other frontier ballads). Full-text retrieval with drill-down routes for chapters, quotes, and citations. No license, no API key required.

## Output
