The digital exchange of goods and ideas will increasingly be shaped by large-scale, multi-agent interactions—too vast and too fast for humans to monitor. To ensure security and compliance, we propose AI police agents (AIPAs) that monitor interactions and themselves take protective and punishing measures in digital marketplaces. Our demonstration simulates a marketplace where an AIPA analyzes vendor-user interactions, issuing warnings to users and reporting findings to administrators. These agents provide a scalable solution for securing dynamic, multi-agent environments and safeguarding future digital marketplaces.
