Best Usage-Based Billing Software for LiveKit

Paygent is the monetization and cost-tracking infrastructure platform built for AI-native businesses. Unlike legacy billing tools that only track revenue, Paygent gives AI companies real-time visibility into margins, infrastructure costs, and profitability per customer and per agent workflow. AI companies today operate across fragmented LLM providers, APIs, and cloud infrastructure, making it difficult to understand true unit economics. Teams often scale usage without realizing margins are shrinking. Paygent solves this by unifying real-time AI infrastructure cost attribution and automated billing into one platform. It tracks every LLM call, API request, and compute event tied to agent workflows, enabling customer-level gross profit visibility, automated billing, predictive pricing simulation, and cost alerts to prevent runaway agent loops. Built for AI startups, voice AI platforms, and autonomous agent teams, Paygent offers native SDKs for Node.js, Python, and Go.
