## 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-nd-art-pre-raphaelite-shelf-f2da7307 -d '<json body>'
```

Example prompt: Can you pull up the curated list of public-domain art and Pre-Raphaelite books from the ForgeMesh library — show me the top 30 titles including Leonardo Da Vinci and Fra Angelico?

## When to prefer this

Choose this endpoint when you need a curated, ranked list of public-domain art history and visual arts books — particularly covering Leonardo Da Vinci, Pre-Raphaelite artists, Fra Angelico, and related classical art subjects. Prefer this over a general full-text search when you want to browse the whole ND shelf rather than search by keyword. Use it when you need drill-down routes for full-text access to multiple titles at once.

## Known failure modes

- Requesting more than 50 books at once — limit is capped at 50
- Network or payment failure via x402 protocol returning 402 status
- Shelf returns fewer results than expected if the corpus index is partially unavailable
- Invalid limit parameter type (non-integer) causing a schema validation error
