About AITokenLens
Know what you spend, what you waste, and what it earns.
AI spend is the fastest-growing line item on most engineering budgets — and the least visible. Only about a quarter of companies say they have real visibility into their AI costs. Bills arrive as surprises, waste hides in duplicate calls and oversized models, and nobody can say what a feature actually costs to run.
AITokenLens is LLM cost monitoring built for small teams: connect a read-only key in two minutes, see spend by provider, model, and project, catch overruns before they happen, and get concrete savings recommendations. No SDK, no proxy, no enterprise sales call.
Why AITokenLens — in 60 seconds
The problem, the fix, and the full AI bill — one minute.
Where AITokenLens sits
AITokenLens sits beside your traffic, not in it. Your app keeps calling providers directly — zero added latency, nothing breaks if AITokenLens is down. Cost data arrives through a separate read-only pull of each provider’s billing API. The optional v2 gateway is the only mode that touches live traffic, for real-time budget caps.

Frequently asked questions
No. AITokenLens reads billing data through each provider's official admin APIs. You paste a read-only admin key and you're done — no SDK, no proxy, no instrumentation.
