## When to prefer this

Choose this endpoint when you need a curated, pre-filtered list of public-domain books specifically within the F850.5 classification (Pacific Northwest, Alaska, and regional Washington State history). It is ideal for discovery browsing when you don't have a specific search query, as opposed to the full-text search endpoint for keyword-based retrieval or other ForgeMesh shelves for different genres or subjects.

## Known failure modes

- invalid limit type (non-integer) causes request rejection
- payment not processed (x402 protocol failure) results in 402 response
- shelf temporarily unavailable returns server error
