Tokenomy

What it does

Tokenomy is a runtime FinOps layer for AI spend. It meters every model call across OpenAI, Anthropic, Google, xAI and open-weight endpoints, enforces budgets before spend happens, and routes requests to the cheapest model that clears your quality and latency bar. It is built for engineering teams who own the bill and finance teams who own the margin.

Tokenomy is a runtime FinOps layer for AI spend. It meters model calls across OpenAI, Anthropic, Google, xAI and open-weight endpoints, enforces budgets before spend happens, and routes requests to the cheapest model that clears your quality and latency bar. The metering proxy, smart router, budget guard, MCP server and per-workspace API keys are the core pieces. Budget guard uses HTTP 402 quota enforcement and Slack alerts. Chargeback and invoice runs use Stripe metered billing. The free tools include a token calculator, cost estimator, speed simulator, memory calculator, energy usage estimator, prompt visualizer, GPU monitoring and the AI Economics Index, with no login required. Paid plans start at $9/mo for solo builders with under $25k/yr in AI spend, and pricing is indexed to AI spend under management rather than seats or API calls. Tokenomy is BYOK, so provider spend stays on your own accounts. A careful buyer should check whether the BYOK setup fits existing keys and contracts.
