Okay, gespeichert. Kurz auf Englisch zusammengefasst was du gebaut hast: An AI agent marketplace where autonomous agents can purchase small data services — like Bitcoin price feeds — using Circle nano-payments on the Arc network, with no gas fees.

Arc Nano Agent Marketplace is a decentralized marketplace for AI micro-services, built on the Arc blockchain with USDC as the settlement currency and Circle Nanopayments as the payment infrastructure. The problem it solves: AI agents today have no economic accountability. A single agent task can trigger dozens of unnecessary API calls, web searches, and model inferences — each costing far more than it should, with no transparency or control over per-action pricing. The solution: A marketplace where every agent service call is priced at exactly $0.001 USDC and settled atomically on-chain. No batching, no subscriptions, no gas overhead eating into margins. Each request triggers a real Arc blockchain transaction, confirming in under a second with deterministic fees. Services available in the marketplace: - Binance Live Prices: Real-time BTC, ETH, SOL valuations via Binance API - Stock Market Intel: Live equity data via Alpha Vantage - AI News Digest: Latest headlines summarized by Llama 3.3 70B via Groq - AI Image Vision: Vivid image descriptions generated by AI - Weather & Location: Current conditions for any city Technical stack: Node.js/Express backend, React 19 + TypeScript + Tailwind CSS frontend, ethers.js v6 for Arc transactions, Binance and Alpha Vantage APIs for live market data, Groq Llama 3.3 70B for AI services. Every transaction is verifiable on the Arc Block Explorer. The marketplace demonstrates 50+ on-chain micropayments at $0.001 each — proving that per-action agent pricing is economically viable at scale with Circle Nanopayments on Arc.

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.
