## 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-gv-shelf-recreation-sports-physical-education-d1a9ffd8 -d '<json body>'
```

Example prompt: Show me up to 30 public-domain books from the GV recreation and physical education shelf on ForgeMesh — I'm looking for classic texts about sports history or physical fitness.

## When to prefer this

Choose this endpoint when you specifically need public-domain books in the GV classification (recreation, sports, physical education, games, dance, leisure). Prefer it over full-text search when you want a broad curated shelf overview rather than passage-level retrieval. Ideal for discovering and cataloging classic physical education or recreation literature without needing an API key.

## Known failure modes

- Limit parameter exceeding 50 returns an error or is capped
- Empty shelf response if catalog indexing is incomplete
- Payment failure (x402) if USDC balance is insufficient
- Slow response if full-text index is being rebuilt
