I built a free JavaScript SDK to track AI API usage and cost

AIProfitHub — Sun, 17 May 2026 09:57:19 +0000

I’ve been building AIProfitHub, a tool for tracking AI API usage and cost across AI products.

One problem I kept seeing: teams ship AI features fast, but they often don’t know which feature, customer, user, or model is creating the cost.

So I published a small JavaScript SDK to make usage tracking easier.

What it does

Track AI usage events
Attribute cost by user, team, feature, customer, and model
Prepare data for budget alerts and cost analysis
Works with OpenAI, Anthropic, and LangChain-style wrappers

Install

npm install aiprofithub-sdk

Basic example

import { createClient } from "aiprofithub-sdk";

const client = createClient({
  apiKey: process.env.AIPROFITHUB_API_KEY,
});

await client.trackUsage({
  provider: "openai",
  model: "gpt-4o-mini",
  feature: "support-chat",
  userId: "user_123",
  inputTokens: 1200,
  outputTokens: 350,
  costUsd: 0.0042,
});

I’d love feedback from developers building AI products:

How are you currently tracking LLM usage, token spend, and cost per feature?
