The data source you and your AI Agents can trust

Canonical editions, works, and contributors — over REST and MCP — so agents look up books instead of scraping pages.

Built for agents

REST and MCP, same key

Commercial-friendly

Who this is for

Agents first. Then the people who ship them.

Typed tools for agents. The same Bearer key for the engineers who ship those agents — and the catalogs they sit in.

AI agents

Typed MCP tools for ISBN lookup, title resolve, search, and recommendations. Stable IDs your agent can cache and cite.

Engineers

The same Bearer key in the apps those agents sit in. Point lookups for catalogs, retrieval, and anything that used to mean a scraper.

Books

Editions, works, ISBNs, synopses. One record per edition, joined to the work.

Authors

Names, keys, and the books they wrote. Same contributor ID on REST and MCP.

Global catalog

119.8M editions and 78.2M works from the current normalize. Release 2026-09.2.

Developer-friendly

REST and MCP, same Bearer key. Markdown docs so agents do not scrape HTML.

Explore the data

A library for the next generation of builders.

Lookup by ISBN. Resolve a title. Search when you only have a phrase. Docs are markdown so agents can read them without scraping HTML.
