Infrastructure and extensibility
The depth behind the four-part loop.
UsageTap gives product teams a focused operating surface without closing off the billing, observability, and internal systems that already run the business.
OpenTelemetry exports
Stream calls, tokens, latency, and cost to OTLP-compatible tools including Datadog, Grafana, and New Relic.
Stripe synchronization
Send validated meter events and keep UsageTap customer plans aligned with the subscriptions Stripe already owns.
API, SDK, and webhooks
Integrate with the TypeScript SDK or plain HTTP, then deliver usage and policy events to internal systems through webhooks.
Simple integration
Add metering to the call you already make.
Wrap your OpenAI, Anthropic, or OpenRouter client. Your existing provider calls stay the same while UsageTap handles metering around them.
Read the SDK reference →Remove the wrapper to roll back
import OpenAI from "openai";
import { withMetering } from "@usagetap/sdk/openai";
// Every existing OpenAI call below stays the same.
const openai = withMetering(new OpenAI(), "cust_123");
const response = await openai.responses.create({
model: "gpt-5.5-mini",
input: "Generate the document",
});A separate product for input cost
Need to reduce the tokens inside each prompt?
UsageTap Compress is purpose-built for prompt efficiency and production evaluation. It complements Meter without blending two different buying journeys.
Usage data and policy, connected
Build the usage experience your product deserves.
Start with metering, then add controls, forecasting, customer visibility, and commerce synchronization when you need them.
