The integration <a href="https://www.coinbase.com/blog/introducing-amazon-bedrock-agentcore-payments-powered-by-x402-and-coinbase" rel="noopener noreferrer nofollow">lets</a> agents built on AWS discover services, sign transactions and settle payments without holding private keys, according to a Coinbase announcement on May 7. A single API call handles authentication and payment routing.
Settlement runs on Base and Solana<a href="https://yellow.com/asset/sol" rel="noopener noreferrer nofollow">(SOL)</a>. Coinbase says transactions clear in roughly 200 milliseconds on Base, at a fraction of a cent each.

Brian Foster, Coinbase's head of infrastructure growth, said enterprises have struggled to clear legal review for agent-driven spending. He framed the AWS deal as a fix for that bottleneck.
"AWS developers can now give their agents financial autonomy in a comprehensive managed solution. It just works," Foster said.
The x402 protocol uses the HTTP 402 "Payment Required" status code to handle machine-to-machine settlement. It is governed by the x402 Foundation, whose members include AWS, Coinbase and dozens of other firms.
According to Coinbase, x402 has processed more than 169 million payments since launch, across over 590,000 buyers and 100,000 sellers in roughly a year.
