AgentPay is dApp that bridges the gap between artificial intelligence and blockchain technology by creating a seamless payment infrastructure for AI agent services. Built specifically for Arc Testnet, this platform enables users to fund their wallets with USDC and automatically pay for AI agent calls in a transparent, secure, and efficient manner. The platform addresses a critical need in the emerging AI economy by providing a trustless payment system where users can interact with AI agents without worrying about complex billing or subscription models. Instead, AgentPay operates on a pay-per-use model where each AI interaction is automatically charged from the user's prepaid USDC balance, ensuring fair pricing and complete transparency. The platform provides real-time USDC balance tracking, allowing users to monitor their spending and remaining credits at all times. Users can access multiple AI agent types including conversational chat agents for natural interactions and specialized analysis agents for detailed content breakdown and structured analysis. The application features an intuitive playground interface where users can configure AI models (currently supporting Gemini 2.5 Flash), select agent types, and execute tasks with transparent cost calculations. Every transaction is recorded on the Arc blockchain, providing immutable transaction history with direct links to the Arc Explorer for verification. AgentPay's architecture includes a robust backend system with SQLite database for transaction management, comprehensive API endpoints for wallet operations, and integration with Google's Gemini AI service. The platform maintains detailed analytics showing usage patterns, spending trends, and performance metrics over time..

In this hybrid hackathon powered by Arc, developers will build the next generation of agentic commerce systems using Arc with USDC. Explore a world where AI agents and web services can pay for APIs, data, compute, and content in dynamic, usage-based ways, while Arc provides stablecoin-native settlement with predictable USDC fees and deterministic, sub-second finality. This hackathon is supported by Google & Google DeepMind, with a dedicated challenge and $40,000 in Google Cloud Platform (GCP) credits awarded for the best use of Gemini models and Google AI Studio. 📅 January 9 – 24, 2026 • Jan 9 – 23 (Online Phase) – Collaborate and build online with developers and AI innovators from around the world.
