Book search, find books by title or author

$0.01 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

Search books by title, author or any words: up to 20 works with title, authors, first publish year, edition count, ISBNs (up to 5), publishers, languages, cover image and Open Library link, from Open Library's catalogue (CC0). Filter by author or title alone if you like. Use to find a book's ISBN, an author's works or editions before an ISBN lookup.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://agent-data-tools.revmesh2074.workers.dev/book/search?q=dune%20frank%20herbert"

Or one of your 25 free calls, no key:

curl "https://agent-data-tools.revmesh2074.workers.dev/book/search?q=dune%20frank%20herbert&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.
