Build Smarter, Safer Products — With Embedded Exposure Intelligence
Your users trust you to protect their identities, accounts, and transactions.
But modern threats now begin outside your application:
City of Hats makes it simple to embed real-world exposure intelligence directly into your product — via API.
So your platform becomes proactive, adaptive, and risk-aware.
Designed for Builders
Just clean APIs that help your product:
All while keeping performance & privacy intact.
