Technical details
Endpoint
POSThttps://library.forgemesh.io/qbWhen to prefer
Choose this endpoint when you need a curated, ranked catalog of public-domain astronomy and space science books (Library of Congress classification QB) without any API key or licensing overhead. Prefer it over a full-text search endpoint when you want a browsable shelf of titles rather than passage-level results, or over generic book APIs when you specifically need free, openly accessible texts in the astronomy domain.
Side effects
- Payment not included or insufficient — endpoint requires $0.003 USDC via x402 protocol
- Limit parameter exceeds maximum of 50 — server may reject or cap response
- Invalid input schema (e.g. non-integer limit) — may return a 400 error
- Network timeout or service unavailability — no cached fallback guaranteed
