## 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-technology-shelf-f810de5d -d '<json body>'
```

Example prompt: Can you pull up the top 20 public-domain technology books from the ForgeMesh library shelf so I can browse what's available?

## When to prefer this

Choose this endpoint when you need a curated, pre-ranked browsable list of public-domain technology books without needing a search query. Prefer it over the full-text search endpoint when discovery and shelf-browsing is the goal rather than retrieving specific passages. It is free of API keys and licensing, making it ideal for automated reading-list generation or educational content pipelines.

## Known failure modes

- Limit parameter exceeds 50 — API may reject or cap silently
- Payment not included or insufficient — returns 402 Payment Required
- Limit set to 0 or negative — may return empty list or validation error
- Network timeout if corpus index is temporarily unavailable
