Catalogue · Books live · More on the way
Up-to-date data, one provider.
Canonical books, authors, and identifiers for engineers and founders who would rather ship product than maintain scrapers — with room for more datasets over time.
Datasets
What you can pull today
Start with books. Expand into adjacent catalogs without switching vendors.
Editions, works, contributors
ISBN lookup, search, stable IDs, redirects, and a changelog you can sync.
Open books API →Contributor graph
Richer author profiles and cross-dataset identity — shipping after books v1 is solid.
On the roadmapNew catalogs over time

One key, several ways in
Inspired by how modern data APIs ship: same credentials across REST, agents, and bulk.
