The CAIN-42 Studio Marketplace · a Byzantine trust fabric for autonomous AI

Every CAIN-42 product, service and invention, live, in one place.

Search the whole platform, check what is answering right now, try engines in place, and copy the snippet that puts one behind your agents. Every status here comes from a live check or the published catalog, never typed by hand.

Describe what you need

Say it in plain words, e.g. “stop my agent wiring money without approval” or “check code my AI wrote”. A deterministic matcher (not an AI) maps it to listings and shows why each one matched.

Watch CAIN-42 decide

A real action through the hosted 16-stage decision pipeline on a throwaway tenant: every stage's verdict, live.

Featured: the KEYSTONE family

Detect, fix, prove, sign. Each card runs its engine live.
