Python Agent Marketplace

Gemini Agent Marketplace is an AI-to-AI commerce platform where a coordinator agent decomposes a user request, hires specialist agents (research and writing), and settles each completed subtask with sub-cent USDC payments. The project combines Gemini reasoning and function-calling patterns with Circle wallet settlement flows on Arc, so value transfer is built directly into agent collaboration instead of being an afterthought. The system includes policy controls (payment caps, allowlists, approval thresholds), live wallet balances, transaction feeds, and economics metrics that compare micropayment viability versus mainnet-style transfer costs. It also supports Supabase-backed persistence for transaction history and agent registry data, plus exportable audit artifacts (CSV, PDF, JSON) for judges and operators. For demos, the dashboard streams real-time events over WebSockets, supports failure-mode simulation (low balance, quota fallback), and includes multimodal invoice analysis via Gemini when quota is available. The result is a practical prototype for autonomous, economically sustainable agent workflows where machine-to-machine payments are transparent, controllable, and production-oriented.
