Example prompt: Can you show me up to 30 public-domain books from the Questions and Answers periodicals shelf on the ForgeMesh library — I'm interested in things like Notes and Queries issues?

## When to prefer this

Choose this endpoint when you specifically want to browse or list curated public-domain Q&A-style periodicals (especially Victorian-era literary journals like Notes and Queries) rather than performing a full-text search or querying a different subject shelf. It is best suited for catalog discovery rather than passage retrieval.

## Known failure modes

- Requesting limit above 50 may return an error or be capped
- Payment failure (x402) if USDC balance is insufficient
- Empty result set if shelf has no indexed books matching the category
- Network timeout if corpus indexing is slow
