## When to prefer this

Choose this endpoint when you need a curated, pre-ranked list of public-domain books specifically from the African American history and autobiography category (Dewey/LC E300 range), rather than running a keyword search across the full corpus. It is ideal for browsing or presenting a shelf of titles rather than retrieving specific passages or searching by query text.

## Known failure modes

- limit exceeds 50 — API may reject or cap silently
- limit is 0 or negative — may return empty list or error
- payment of 0.003 USDC not provided — x402 payment required error
- network timeout or server unavailability — no results returned
