arc-shopper is an experimental autonomous commerce agent that demonstrates machine-to-machine purchasing using the x402 HTTP Payment Protocol. It showcases a fully integrated end-to-end flow where an AI-driven agent autonomously discovers products, evaluates them, and completes purchases without manual checkout interaction, enabled by cryptographically-signed payment authorizations embedded directly within HTTP request/response cycles. At its core, arc-shopper implements a protocol extension to HTTP that eliminates traditional user checkout interactions. When a server returns a 402 Payment Required response, the client automatically constructs a signed payment payload according to the x402 specification, performs payment settlement on a blockchain testnet, and then retries the request to receive the gated content. This flow is supported from wallet provisioning through on-chain settlement and content delivery, demonstrating autonomous digital commerce. The system’s architecture consists of three main layers. The Client Layer authenticates users and provisions wallets, either via a primary custodial wallet service or a fallback deterministic wallet. The Agent Layer includes an LLM-powered shopping agent that interprets user queries, performs product searches, extracts purchasing intent, and applies a policy engine to enforce spending limits, daily caps, and category restrictions. The Payment Layer constructs EIP-712 signed x402 payloads and interacts with a local facilitator service to verify and settle transactions on the Arc testnet. Once payment is confirmed, the originally requested content is served. The repository also includes a digital product catalog API, wallet and payment facilitation endpoints, and a complete backend running on Node.js with TypeScript. It serves as a proof-of-concept for autonomous commerce agents that leverage cryptographic payment flows and blockchain settlement to perform digital purchases without human checkout steps.

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.
