Revenium helps you bring visibility, accountability, and control to your AI and digital product costs. Our APIs power a full-stack monetization and FinOps platform that tracks every transaction, API call, and AI inference with cost, performance, and usage context—so you can shift from reactive cost management to proactive optimization and monetization.

Whether you’re running a large-scale AI deployment or exposing internal services to external partners, our platform makes it easy to track usage, create usage alerts, enforce policies, and define billing models that match your go-to-market. You can convert any usage data you send to Revenium—including token counts and automatically calculated costs—into subscription plans, usage-based pricing, or hybrid monetization models, all backed by API-driven automation. Lastly, you can define usage and spending thresholds to trigger alerts or automated actions, so you’re never surprised by unexpected AI costs again.

AI Metering API & Related Middleware

Our AI Metering API is the ingestion point for all AI-related metadata into our platform. We also publish several SDKs that simplify the process of sending AI transactional metadata to Revenium. For most use cases, the middleware provides the easiest integration path for AI metering. The metering API and middleware allow you to meter AI usage by tokens, cost, or latency, and associate that usage to customers, tiers, agents, subscription plans, and much more. It provides a foundation to understand spend, optimize workloads, and enable usage-based billing for AI-powered products.
