Payment Acceptance is Coinbase’s full-lifecycle stablecoin payment API for PSPs, marketplaces, and enterprise platforms. It has native x402 support, so any payment session you create can be authorized by an x402-enabled agent instead of (or alongside) a human wallet or Coinbase account, using the same session, capture, void, and refund primitives you already use for the rest of your checkout.

​
How it works

Every payment session created with a wallet target includes an x402Url. Hand that URL to an x402-enabled agent and it authorizes the session itself, submitting a signed payment payload to .../authorizations/x402 through the standard x402 402-challenge/response flow. There’s no separate integration path: it’s the same payment session your web checkout already uses.

​
Set up

Payment Acceptance requires onboarding with the Coinbase team. Get in touch to start. Once you have API access, see x402 authorization for the request and response details, and Payment Sessions for the x402Url field.
