Checkout API
Overview
The Checkout API provides everything you need to accept stablecoin payments in your application. Whether you’re building an e-commerce platform, a SaaS product with subscriptions, or collecting one-time payments, our API makes it simple to accept crypto payments with the stability of fiat currencies.
Exodus Business Required: To use the Checkout API, you need an Exodus Business account. Contact our sales team at [email protected] to get started.
Features
-
Checkouts: Create secure checkout pages to accept one-time payments via stablecoins. Fully customizable with your brand colors, logo, and styling.
-
Subscriptions: Recurring stablecoin billing via on-chain authorizations. Customers sign once on a Subscription Checkout — first charge is atomic with the subscribe. Each cycle is then driven by a merchant-signed
POST /subscriptions/:id/charge. Caps are enforced on-chain forever; price changes never re-prompt the customer. -
Two-Step Payments: Process payments in two steps, deferring the decision to charge or refund, while holding user funds in an escrow account. Charges and refunds are fully automated via signed requests.
-
Crypto to Fiat: Receive payments in stablecoins or in your local currency.
-
Payouts (Beta): Pay a bank account in fiat with crypto. A customer completes KYC once and sends crypto; we off-ramp it and deliver fiat to a beneficiary’s bank. Unlike checkouts, this flow is API-first (you render the payment UI, we return deposit addresses). See Payouts.
Supported Stablecoins
The Checkout API supports the most widely-used stablecoins across popular networks:
| Stablecoin | Networks |
|---|---|
| USDC | Ethereum, Solana, Polygon, Arbitrum, Base, BSC |
| USDT | Ethereum, Solana, Polygon, Arbitrum, Base, BSC |
How It Works
- Create a checkout or subscription - Make an API call to generate a payment session
- Redirect your customer - Send them to the hosted payment page
- Customer connects wallet and pays - The customer approves the stablecoin transfer from their wallet, or sends funds directly to the deposit address. For subscriptions, they sign a recurring authorization once and the first charge settles immediately.
- On-chain confirmation - Payment is confirmed on the blockchain
- Receive confirmation - Get notified via webhooks when the transaction is confirmed
