Autlantic BillingUSDC on Base

TypeScript SDK and hosted API for USDC subscriptions, one-time payments, and shareable payment links. Non-custodial settlement to your EVM wallet. Test and Live keys.

npm SDK

@autlantic/payments-recurring: subscriptions, one-time payments, payment links, refunds, and webhooks. TypeScript, Node 20+.

Payment links

Fixed-amount shareable URL and QR. Payer opens hosted checkout; USDC settles to your wallet.

Hosted API

REST with API key when you do not want Node in your stack. Same billing engine as the SDK.

Test and Live

abk_test_ keys on Base Sepolia, abk_live_ keys on Base mainnet. Same Test / Live split as the merchant portal.

Two ways to integrate

Mode	Best for
npm SDK	Node backends, in-process sandbox, full control
Hosted HTTP API	Any stack (curl, mobile, PHP), API key only

bash

npm install @autlantic/payments-recurring

import { AutlanticBilling } from "@autlantic/payments-recurring";

// Hosted: set AUTLANTIC_BILLING_API_KEY to abk_test_… or abk_live_…
const billing = AutlanticBilling.fromEnv();

// Or local in-process demo:
// const billing = AutlanticBilling.sandbox({ merchantId: "mer_demo" });

const { url } = await billing.createPaymentLink({
  merchantRefPrefix: "invoice",
  payoutAddressEvm: "0xYourMerchantWallet…",
  amountUsdc: 42,
  description: "Consulting",
});
// Share url or QR → /checkout/link/:id
