What is Vluna?

Vluna is billing and runtime usage control for AI agents.

It helps you ship agentic features that are safe to run, easy to monetize, and easy to explain when something goes wrong.

Who it is for​

Vluna is for developers building:

  • AI agents that run multi-step tasks and call tools.
  • Agent products that must track real usage and cost per task run, enforce budgets and entitlements, and keep an auditable trail for pricing and support.
  • Agent products that price by outcome or value, and need a billing engine that turns business events into billable results with clear terms and reporting.

What Vluna does​

Vluna provides:

  • Runtime authorization and limits (authorize before work, commit after work).
  • Usage-based metering and settlement for agent workloads (tokens, requests, time, bytes).
  • Outcome-based billing when value is measured by results (events to ratings).
  • Plans, entitlements, and wallet mechanics (credits and grants).
  • An auditable ledger and reporting surfaces for reconciliation.

How money works (XUSD)​

AI costs change fast and are hard to explain to customers in raw units. Vluna solves this by settling all monetary amounts in a single internal currency called XUSD. XUSD is stored as an integer to keep accounting precise and audit-friendly.

XUSD is not a customer-facing unit. In your product, you can present any credit system you want, while Vluna keeps the internal settlement and ledger consistent.

When you need it​

Use Vluna when you have one or more of these problems:

  • You need to stop or degrade work when a customer runs out of budget.
  • You need reliable retries without double-charging (idempotency).
  • You need to price usage while preserving an audit trail.
  • You need to bill by outcomes and business results, not just raw usage.
