## 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-nutrition-shelf-eb8d5f1d -d '<json body>'
```

Example prompt: Can you pull up the top 20 public-domain nutrition books from the ForgeMesh library shelf so I can browse titles like Human Foods and Their Nutritive Value and The No Breakfast Plan?

## When to prefer this

Choose this endpoint when you need a curated, ranked list of public-domain nutrition and diet books without requiring an API key or license. It is ideal for research assistants, bibliography builders, or reading-list generators focused on historical nutrition literature. Prefer this over a general full-text search endpoint when you want a browsable shelf of titles rather than passage-level results for a specific query.

## Known failure modes

- Invalid limit value (e.g. exceeding 50 or non-integer) may return a validation error
- Payment failure via x402 protocol returns a 402 status with no book data
- Server unavailability returns a 5xx error with no results
- Empty shelf (unlikely but possible if index is rebuilding) returns an empty list
