Kong has acquired open source platform OpenMeter to integrate real-time metering and billing into its API platform, enabling AI-ready usage-based monetisation.
Kong Inc., the cloud API company, has acquired OpenMeter, an open source and SaaS platform for usage-based metering and billing. The move is designed to add usage-based monetisation capabilities to Kong Konnect, the company’s unified API platform.
With OpenMeter integrated, Kong aims to help organisations productise and bill for APIs, large language models (LLMs), and data streams. In the AI era, billing is no longer a traditional subscription challenge but a metering problem. AI agents can trigger thousands of API and data calls per second, demanding scalable, precise billing systems that operate at machine-driven speed.
“As businesses scale and AI adoption grows, organisations need simple, turnkey solutions to meter and monetise digital consumption in real time. With OpenMeter joining Kong, we’re enabling customers to turn their APIs, data and AI capabilities into new revenue streams. Thus making monetisation native, scalable and ready for the agentic AI era,” said Augusto Marietti, CEO and co-founder of Kong Inc.
OpenMeter’s core technology will be embedded into Kong Konnect to support usage measurement, billing, and management across APIs, LLMs, and event streams. Integration is scheduled for early 2026, with customer migration expected by mid-2026. In the meantime, OpenMeter Cloud will continue operating normally, offering enhanced capabilities, multi-region deployment, and stronger compliance and security.
OpenMeter’s engineering and design team, including co-founders Peter Marton and Andras Toth, will join Kong, which plans to expand investment and resources for further development.
Crucially, OpenMeter will remain an open source project under Kong. This ensures ongoing community-driven innovation while delivering commercial-grade monetisation tools inside Konnect, striking a balance between transparency and enterprise readiness in the evolving API economy.
