Coinbase Payment Acceptance enables payment platforms, PSPs, and enterprises to offer stablecoin checkout to their customers. Buyers pay with USDC (and soon USDT) from any of 500+ wallets, directly from their Coinbase account, or through an x402-enabled agent. You get instant settlement in USD or USDC through APIs that work like the card networks you already know.

​
Why stablecoins

  • A customer base you can’t reach today. Over 150 million people hold stablecoins globally. This is net-new demand, not a substitution for existing card volume.
  • No chargebacks. Cryptographic authorization replaces dispute-based payment models.
  • Instant settlement. Funds settle in seconds, not days. No rolling reserves, no holdbacks, no batch windows.
  • Borderless by default. Buyers pay from anywhere in the world, 24/7. No cross-border fees, no FX conversion, no correspondent banking.

​
What you get

Authorization, capture, void, and refund. Same lifecycle your systems already support.

​
How it works

  1. You create a payment session via API with an amount and currency.
  2. The buyer authorizes the payment from their wallet, Coinbase account, or x402-enabled agent.
  3. You capture funds after fulfillment, instantly settled to your account.
  4. Refunds and voids work exactly like card payments.

​
x402 agent payments

Payment sessions created with a wallet target include an x402Url, a CDP-hosted URL that you can give to an x402-enabled agent. The agent makes a POST request to this URL. CDP returns the x402 payment requirements in the PAYMENT-REQUIRED header, including the supported USDC payment options. After the agent completes the x402 payment flow, the payment session follows the normal Payment Acceptance lifecycle. You can capture, void, or refund the payment session using the same APIs as other wallet-authorized sessions.

​
Who this is for

Payment Acceptance is designed for payment service providers, marketplaces, and large-scale commerce platforms looking to add stablecoin checkout as a payment method.
