Open Library

Connects Claude to the Internet Archive's Open Library API for querying book metadata, author information, and bibliographic data. The source doesn't list specific tools, but this is part of Pipeworx's gateway approach where you can ask questions in plain English using ask_pipeworx instead of calling individual tools directly. It handles tool selection and argument mapping automatically. Useful when you need to look up ISBNs, search for books by title or author, or pull catalog data without manually constructing API calls. Available as a standalone endpoint or through the full Pipeworx gateway that bundles 250+ data sources.
