# The Economic Runtime for AI — make every AI dollar accountable.

> Control every AI dollar before it is spent. Tokenomy meters every LLM and agent call, enforces budgets in the request path, routes to the cheapest model that clears your quality bar, and puts an effective-dated price record behind every number. BYOK across OpenAI, Anthropic, Google, xAI and open-weight endpoints.

Tokenomy meters, budgets, routes and charges back every model call across OpenAI, Anthropic, Google, xAI and open-weight endpoints. Bring your own keys — provider spend stays on your accounts. Two doors: engineering teams who own the bill, and finance teams who own the margin and the forecast.

## For engineering: meter, enforce, route

Agent-level attribution down to the step and tool call. Budgets with hard and soft caps that fire before spend, not after. Smart routing to the cheapest model that still clears your quality and latency bar.

## For finance: margin, forecast, commit, chargeback

Gross margin per customer and per feature, spend forecasts with a stated confidence band and month-end accrual, commitment burn-down against Azure, AWS and Anthropic contracts, and chargeback that survives audit.

## Prove it

Chargeback exports, SLO monitoring, invoice runs and executive PDFs. Show finance, security and product exactly which AI dollar produced which outcome.

## Runtime rails, not dashboards
