Features as a Service
Request a feature by name.
Casteo computes machine-learning features on demand. Call one by name over the API and the result comes back — no pipeline to run, no infrastructure to keep alive.
How it works
Call it by name
Make an API request naming the feature you need. That’s the whole interface — no model to configure, no job to schedule.
Computed internally
Casteo calculates the feature on its own infrastructure and returns the result to you.
Use the result
Feed it straight into your product, your model, or your decision logic.
Your features stay yours.
Features are calculated internally and are never visible to other users. A caller receives a result — not your definition, not your data, not the logic behind it.
Sell what you build.
Any feature you build can be offered to other users for a price. They call it by name like any other feature, and how it works stays private to you.
