OpenFlow™: Software Development Kit (SDK)-v.1.0.2

OpenFlow™ is a programmable monetisation engine built for the agentic economy, where APIs, AI agents, and digital services exchange value in real time. Traditional systems fail to support high-frequency, low-value transactions due to latency, batching, and gas costs, making per-action pricing impractical. OpenFlow solves this by enabling deterministic, sub-cent payments using USDC on Arc with Circle Nanopayments. At its core, OpenFlow introduces an economic execution layer (settlement layer) where every interaction—API call, compute task, or agent action—is a billable event. Transactions settle instantly on-chain, allowing precise usage-based pricing without subscriptions. The architecture consists of four layers: execution (Arc + USDC settlement), monetisation (per-request pricing and metering), agent interaction (AI agents triggering payments via APIs), and application (marketplaces and micro-commerce systems). Anchored as a per-API monetization engine, OpenFlow also enables agent-to-agent payments, usage-based billing, and real-time micro-commerce. Our demo includes 50+ on-chain USDC transactions representing API calls, agent payments, and compute usage, all priced at sub-cent levels. OpenFlow transforms APIs into revenue-generating endpoints and AI agents into autonomous economic participants, establishing a scalable foundation for machine-to-machine commerce.
