PolicyKit

AWS IAM for AI Agent Spending

PolicyKit is a financial authorization layer for autonomous AI agents. Before an agent can make any paid API call, provision cloud resources, or execute a financial transaction, PolicyKit evaluates the request against configurable policies, budgets, and approval workflows.

Why?

AI agents can spend real money, but they lack financial access controls.

Without authorization, a prompt injection, hallucination, or software bug can lead to:

Uncontrolled API spending
Unexpected cloud costs
Unauthorized vendors
Missing audit trails
Compliance risks

PolicyKit ensures every spending decision is authorized before funds leave the wallet.
