Billing infrastructure for AI applications
Add AI billing to your app in 5 minutes. Dollar-denominated wallets, multi-provider API, developer markup.
Three steps to AI billing
Integrate once, bill any AI model. No provider accounts to manage, no token math to get wrong.
Get your API key
Create an account and generate an API key. Start building immediately with your developer balance.
Make your first request
Point the OpenAI SDK at Quota. Your existing code works — just change the base URL and API key.
Add billing to your app
Let users pay for their own AI usage with dollar-denominated wallets. Set a markup and earn revenue on every request.
Everything you need to manage AI spending
Whether you are a user checking your balance or a developer building AI features, Quota has you covered.
Real-time balance
Check your dollar balance instantly. See exactly how much you have remaining and what you have spent, just like checking your bank account.
Transparent ledger
Every transaction is recorded in an immutable ledger. See what each AI call cost in dollars, which app made the request, and when it happened.
OpenAI compatible API
Developers can integrate Quota with a single line change. Same API format as OpenAI, with automatic billing and balance tracking.
Never go negative
Your balance is protected. Requests that would exceed your balance are blocked before they happen, so you are always in control of your spending.
One line to get started
Quota works with any OpenAI-compatible client. Just change the base URL and you are ready to track AI usage with credits.

import OpenAI from "openai";
// Just change the base URL
const client = new OpenAI({
baseURL: "https://api.usequota.ai/v1",
apiKey: process.env.QUOTA_API_KEY,
});
// Use it exactly like OpenAI
const response = await client.chat.completions.create({
model: "gpt-4o",
messages: [{ role: "user", content: "Hello!" }],
});
// Credits automatically deducted from balance
