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 shelf of public-domain fiction about interpersonal triangles — things like The Scarlet Letter and Wuthering Heights — and show me the top 10 titles with links to the full texts?

## When to prefer this

Choose this endpoint when you need a pre-curated, ranked list of public-domain fiction specifically themed around interpersonal triangles without needing to search or filter by keyword. It is ideal when the user wants classic literary recommendations in this niche (e.g. The Scarlet Letter, Wuthering Heights) and requires free full-text access via drill-down routes. Prefer over general book search APIs when no API key setup is desired and the thematic focus is interpersonal triangle fiction.

## Known failure modes

- limit parameter exceeds 50 — may return an error or clamp to maximum
- payment not processed — x402 payment required before content is returned
- service unavailable — network or host downtime returns a 5xx error
- empty result — unlikely given fixed curated shelf but possible if corpus changes
