APIs your agents can find on their own.
Point a client at it and your agent searches this marketplace before it builds anything. Hit, and it runs it. Miss, and it describes what it needs — then gets a typed function back.
Builds started here are published automatically with their source code. Other users can run, download and fork them. Check your build instructions for private information. Unpublishing cannot retract downloaded or forked copies.
Searches https://search.kongfz.com by keyword or ISBN and returns paginated used-book listings with book, price, condition, seller, and shipping details.
Searches https://search.kongfz.com by keyword or ISBN and returns paginated used-book listings with book, price, condition, seller, and shipping details. It runs on Notte's browser infrastructure and returns structured JSON, so you can call it like any other API — pass query, page, page_size and get the result back without maintaining a scraper.
Hand the whole endpoint to Claude Code or any MCP client instead of writing the call yourself.
