Do these problems sound familiar?

Multiple APIs to integrate?

You need data from five different sources, each with its own auth, its own rate limits, its own flavour of broken. One goes down and your whole pipeline stalls.

You can't trust what comes back?

Missing ISBNs. Outdated prices. Fields that exist for some books but not others. You're spending too much time fixing bad or missing data.

Sprints lost to someone else's breaking change?

A provider changes their schema and suddenly it's your problem. Again. You planned to ship a feature this week — instead you're fixing an integration.

What if one book API gave you everything?

Unified metadata

Titles, authors, formats, ISBNs, and cover images from multiple data sources, normalized into a single consistent schema.

Near real-time pricing and availability

Current prices and stock status from multiple retailers, updated continuously so your data is never stale.

Proactive data discovery

If we don't already have the data you need, we go and find it. Bookbase actively searches online sources so you never hit a dead end.
