AgentBuy Bridge is a practical demonstration of autonomous commerce using Circle's nanopayment technology. After paying only $0.005 USDC (gas-free on Arc via the x402 protocol), users receive direct access to ASDBUY's official spreadsheet containing shipping agencies, costs, and popular product recommendations. The tool shows a complete end-to-end flow: - Clean UI with visible payment pipeline (Request → 402 Payment Required → Zero-gas EIP-3009 authorization → Batched settlement) - Real receipt showing the micro-transaction - Clickable link to ASDBUY's actual spreadsheet shared by the owner This project highlights how sub-cent micropayments can power real-world use cases in cross-border e-commerce — especially for rep clothing hauls and sourcing from 1688/Taobao agents like ASDBUY. It solves a key pain point: making frequent small economic decisions (like unlocking supplier data) economically viable without expensive gas fees. **Tech Stack:** - Circle Nanopayments + x402 protocol on Base Sepolia - Gas-free micropayments using GatewayWalletBatched - React frontend with animated payment pipeline - Node.js backend The project is built to be a foundation for future AI agents that can autonomously decide when to pay for sourcing data and complete commerce tasks.

In this hybrid hackathon powered by Arc and Circle, developers will build the next generation of Agentic economic applications using Circle’s Nanopayments infrastructure with settlement on Arc in USDC. For the first time, high-frequency, usage-based transactions between users, APIs, and AI agents can operate without gas overhead eroding margin. Arc provides stablecoin-native settlement with predictable, dollar-denominated USDC fees and deterministic, sub-second finality — enabling real-time coordination and economically viable per-action pricing at scale. 📅 April 20 – 26, 2026 • Apr 20 – 25 (Online): Submit projects by Apr 25. • Apr 25 (On-site Build – SF, CA): Teams refine projects. • Apr 26 (On-site Demos & Awards – SF, CA): Live pitches & winners announced.
