Protect margin
Keep expensive usage inside policy.
Check allowances, limits, and overage rules before an AI call, agent action, or API request creates cost.
Usage infrastructure for AI and API products
Meter every valuable action, enforce plan limits before expensive work starts, forecast customer runout, and send trusted usage to Stripe or the commerce systems you already use.

Three commercial outcomes

Protect margin
Check allowances, limits, and overage rules before an AI call, agent action, or API request creates cost.

Give customers clarity
Embed current consumption, allowance, forecast, and the next useful action directly inside your product.

Act before runout
See which customers are approaching a limit, behaving unusually, or ready for a larger package while there is time to respond.
One operating loop
Instrument once, then change commercial policy as pricing and customer behavior evolve.
Capture the product events that create value and variable cost.
Apply customer allowances, limits, throttles, and overage policy.
Predict runout, changes in behavior, and expansion signals.
Send validated usage to Stripe or the systems you already use.
One reversible wrapper, every existing call
Keep the OpenAI, Anthropic, or OpenRouter calls you already ship. UsageTap wraps the client to meter outcomes, apply policy, and feed forecasts and billing. Remove one wrapper to roll back.
Read the full integration guide →import OpenAI from "openai";
import { withMetering } from "@usagetap/sdk/openai";
const openai = withMetering(
new OpenAI(),
"cust_123",
);
// Existing OpenAI calls stay the same.
const response = await openai.responses.create({
model: "gpt-5.5-mini",
input: "Generate the document",
});Design before you deploy
Model credits, actions, workflows, or hybrid usage pricing with your own costs and customer assumptions. Then use the result to guide your Meter setup.
A useful first decision
A separate product for input cost
UsageTap Compress protects critical text, removes low-value context, and gives you an inspectable result to evaluate before production rollout.
Start with real usage
Connect your first customer and meter, then add controls, forecasts, customer visibility, and commerce sync as you grow.
