Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

Example prompt: Can you pull up the curated E456 shelf on ForgeMesh Library and show me up to 30 public-domain books about American exploration and Lincoln — I want titles with links so I can read the full text?

## When to prefer this

Choose this endpoint when you need a pre-curated, ranked list of public-domain books specifically from the E456 collection (exploration, Americana, Lincoln writings) with drill-down access to full texts. Prefer this over the full-text search endpoint when you want to browse the shelf holistically rather than query for specific passages, and over other shelves when your interest is specifically in adventure, exploration, or Lincoln-era American writing.

## Known failure modes

- shelf E456 returns fewer than requested books if total corpus is smaller than limit
- network or service unavailability returning 5xx errors
