StellarTools is a payments platform built on Stellar. You can use it to accept crypto payments, run subscriptions, charge by usage, and pay out to local currencies. Payments settle in a few seconds for fractions of a cent. What you can build with it:
  • One-time and recurring checkout pages
  • Subscription billing with pause, resume, and cancellation
  • Metered billing for AI apps, file uploads, or any usage-based product
  • Customer portals where users manage their own subscriptions and invoices
  • Global payouts to local currencies (NGN, KES, GHS, and more)

​
Get your API key

Go to dashboard.stellartools.dev/api-keys and create a new key. The key encodes your environment (testnet or mainnet), so you do not need to set any base URLs or environment flags.
Use testnet keys while building. Switch to a mainnet key when you are ready to go live.

​
Install the SDK

npm install @stellartools/core

import { StellarTools } from "@stellartools/core";

const st = new StellarTools({
  api_key: process.env.STELLAR_TOOLS_API_KEY!,
});
That is all the setup you need. From here, st.customers, st.checkout, st.subscriptions, and the rest are ready to use.
