The Monetization Layer: How We Built Subscription Intelligence Into Every Agent

AI Monetization Is Hard

Most AI products bill on flat SaaS subscriptions while paying per-token to model providers. This creates a dangerous margin squeeze as usage scales.

The Legenyx Approach

We treat every AI interaction as a billable event:

  • Subscription Tiers: Public → Starter → Professional → Enterprise
  • Feature Gating: Agent access, model tiers, memory limits, analytics access — all tier-dependent
  • Usage Tracking: Token consumption, interaction count, latency — logged per session
  • Cost Analytics: Admin dashboard shows real-time cost per user, per agent, per model

Architecture

The Think Engine checks subscription tier before routing to any agent. Feature flags control which capabilities are active. Usage logs feed analytics and billing.

What This Enables

Granular pricing: charge for what's actually consumed. Transparent margins: know exactly what each user costs. Predictable scaling: model costs scale linearly with verified revenue.
