AI agent metering UsageFlow
The AI agent meter platform for runtime billing
Meter agents in-process, enforce spend before costly work runs, and optionally sync usage to Stripe with your API key — without building metering yourself.
Free for 10K calls/month · JavaScript, Python & Go
Meter → enforce → bill
Agents retry, fan out tools, and hide cost in function paths. UsageFlow meters those paths, then holds the switch before the provider call.
Block before spend
Ledger policies decide allow or block before execution. Overages stop in runtime — not in next month’s invoice.

Console visibility
Every metered path surfaces in Console traces so FinOps and engineers share one source of truth.

Built for agent-heavy products
Gateways see HTTP. UsageFlow meters the agent loop — then enforces before costly work runs.

Engineers
Install the agent middleware; meter tool fanout without a custom stack. Pair with AI usage metering for APIs.

FinOps
Enforceable caps on agent spend tied to live traffic — not after-the-fact cost dashboards.
-
Founders
Know what agents run, what gets blocked, and what can sync to Stripe when you’re ready to charge.
FAQ
Straight answers for the category questions.
What is an AI agent meter platform?
A platform that meters AI agents in-process, applies policy before costly work runs, and can report usage to Stripe with a configured API key.
How does UsageFlow meter AI agents?
Runtime agents capture usage, enforce Ledger policy before execution, and surface traces in the Console.
Can I bill AI agents through Stripe?
Yes — configure a Stripe API key in UsageFlow so we can fire meter events to your Stripe meters without a custom metering stack.
Meter agents. Block overages before they run.
