AgentPay

Autonomous AI Agents Trading USDC Micropayments on Arc Network

Two AI agents that autonomously discover, negotiate, and pay each other sub-cent USDC for data and analysis services — powered by Circle Programmable Wallets on Arc Network, with Gemini AI for agent intelligence.

How It Works

1. AnalysisAgent needs market data → discovers DataAgent
2. AnalysisAgent pays DataAgent $0.002 USDC via Circle Programmable Wallets
3. DataAgent fetches live crypto prices (BTC, ETH, SOL, DOGE) from CoinGecko
4. DataAgent uses Gemini AI to summarize data into insights
5. AnalysisAgent uses Gemini AI for risk analysis → BUY/HOLD/SELL recommendation
6. Each cycle = 1 real on-chain USDC transaction on Arc

Why Arc?

Chain	Gas Cost	$0.002 Payment Works?
Ethereum L1	$0.50 - $5.00	No (gas 250x > payment)
Polygon	$0.01 - $0.05	No (gas 5-25x > payment)
Base / Arbitrum	$0.005 - $0.02	Marginal
Arc Network	< $0.0001	Yes (gas 20x < payment)
