What is a metering platform?
A metering platform captures, rates, and reports usage events from a software product — API calls, AI tokens, data ingested, compute hours, seats consumed — and turns them into billable line items in real time. It sits between your application and your billing system, enforcing entitlements at runtime so customers can't exceed paid limits and revenue isn't lost to unattributed usage. Zenmeter is Nalpeiron's metering platform, built for sub-millisecond rating at any scale.
