About Onaro

Onaro Meridian is FinOps for agentic AI: the system of record that attributes, controls and books what AI agents spend. Meridian meters AI spend from model providers, gateways, agent runtimes and private inference, and attributes it to agents and cost centers: directly when the source identifies them, and through mapping rules when it doesn't. It tracks budgets per agent and cost center with alerts, and posts accruals, chargeback and journal entries to the general ledger, with every journal line traceable to the spend records behind it.

Finance teams use Meridian to close the month on AI spend the way they close everything else. The attribution layer is the open OASA specification, published under CC BY 4.0.
