## 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-ag-shelf-9e22938a -d '<json body>'
```

Example prompt: Can you pull up the AG shelf from the ForgeMesh library and show me up to 30 books — I'm looking for encyclopedias and reference works like the Nuttall encyclopædia that are freely available?

## When to prefer this

Use this endpoint when you specifically want to browse the AG subject shelf of public-domain books on ForgeMesh, particularly for reference works, encyclopedias, or multilingual word lists. Prefer the full-text search sibling endpoint if you need passage-level retrieval rather than a shelf listing.

## Known failure modes

- Limit exceeds 50 — API may reject or cap results
- Network timeout if full shelf metadata is large
- Payment failure (x402) if USDC balance is insufficient — endpoint costs $0.003 per call
- Empty result if shelf index is temporarily unavailable
