## 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-tt-technology-crafts-curated-shelf-63d3fa4a -d '<json body>'
```

Example prompt: Show me up to 30 public-domain books from the TT crafts and technology shelf — things like woodworking, practical mechanics, and needlework.

## When to prefer this

Choose this endpoint when you need to browse or list public-domain books specifically in the technology, crafts, mechanical arts, or handicrafts domain (Dewey TT class). Prefer this over full-text search when you want a curated, ranked overview of available titles rather than passage-level results. Use when building reading lists, research bibliographies, or discovering what texts are available before diving into full-text retrieval.

## Known failure modes

- limit exceeds maximum of 50 — API may clamp or return error
- limit is 0 or negative — may return empty list or validation error
- network or payment failure — 402 payment required if USDC micropayment is not processed
- shelf returns fewer than requested if fewer than 'limit' books are indexed
