Technical details
Endpoint
POSThttps://library.forgemesh.io/heWhen to prefer
Choose this endpoint when you need to browse or enumerate public-domain books specifically about transportation, ocean navigation, railroad history, or communications history (Library of Congress HE classification). Prefer this over full-text search when you want a curated overview of what's available on the shelf rather than searching for specific passages or keywords. It's also the right choice when you want drill-down routes to follow up with full-text retrieval.
Side effects

- Network or payment processing failure returns no results
- Shelf may return fewer than requested books if the total catalog size is smaller than the requested limit
- Malformed request body may result in a 400 error
