## When to prefer this

Choose this endpoint when you need a curated, pre-ranked list of public-domain books specifically scoped to the US Civil War era. It is ideal for building reading lists, seeding a text corpus, or discovering classic Civil War literature without needing a search query. For free-text search across all topics use the full-corpus search endpoint; for other historical periods use the broader history shelf.

- Payment of $0.003 USDC not provided or fails x402 protocol — request rejected
