## 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-nk-decorative-arts-shelf-75317e3f -d '<json body>'

Example prompt: Can you give me a list of up to 30 public-domain books from the decorative arts shelf — things like tapestry, wood carving, and household design — so I can browse what's available?

## When to prefer this

Choose this endpoint when you need a curated, ranked list of public-domain books specifically in the NK (decorative arts, design, crafts) subject area. It is ideal for browsing or enumerating available titles before drilling down into full text. Prefer it over a full-text search endpoint when you want a shelf overview rather than passage-level results, and over general web search when you need guaranteed public-domain status and structured drill-down routes.

## Known failure modes
