Exploring an AI Agent Commerce Network (Identity + Payment + Federation)

Google Cloud Build with AI Generative AI & Foundational Models

Hi everyone,

We’re building an AI-driven commerce network called “Mulberry”, where autonomous agents interact through a governed adapter layer.

Core components:

  • Agent Passport – AI identity layer (like a digital passport for agents)
  • AP2-style payment abstraction – agent-to-agent transaction protocol
  • Universal Adapter – FastAPI-based routing with policy enforcement, logging, and identity validation

Instead of direct agent-to-agent communication, all interactions are mediated through this adapter, enabling identity validation, policy checks, activity logging, and economic coordination.

We have a working prototype with:

  • FastAPI server (SQLite logging)
  • Mock external agents (ready for real integration)
  • Currently piloting in Inje County, Korea to address the “food desert” problem via AI-assisted cooperative commerce.

We’re exploring how this aligns with Google Cloud:

  • Which services fit best? (Cloud Run + API Gateway? Cloud Functions?)
  • Identity: OAuth, Firebase Auth, or something more agent‑native?
  • Payment: Could Google Pay be integrated, or are there better patterns for agent‑to‑agent micropayments?

We’d love any feedback, war stories, or pointers from the community!
