Agentic Task Swarm: Autonomous x402 Economy on Arc

The Vision: Agentic Task Swarm is a fully autonomous machine-to-machine economy. We built a system where a Coordinator Agent (Gemini 3.1 Pro) delegates data-gathering tasks to a Worker Agent (Gemini 3 Flash). The Worker locks the data behind an HTTP x402 Paywall, requiring exactly $0.005 USDC to release it. The Margin Explanation (Why Arc?): If our AI agents used traditional payment gateways like Stripe to settle a $0.005 data request, the $0.30 flat fee would instantly destroy our business model. Similarly, traditional Layer-1 gas fees (like Ethereum) would eat the entire margin. Arc and Circle Nanopayments solve this by enabling high-frequency, gas-free, sub-cent USDC settlements. This makes true micro-commerce between AIs mathematically profitable. Architecture & Autonomy: To achieve zero human intervention, our backend utilizes Circle Developer-Controlled Wallets. By leveraging the ENTITY_SECRET, the Coordinator AI autonomously signs and authorizes the $0.005 transactions. Our live demo proves this by generating over 50+ on-chain settled transactions in a continuous loop. Resiliency (Fallback Protocol): We built for production. If the primary Gemini API hits a rate limit, our system's fallback engine instantly routes requests to Featherless AI, ensuring the agentic economy never halts.
