Coinbase CEO says 'x402' will eventually go mainstream

Coinbase CEO Brian Armstrong said on social media, "x402 is going to be huge eventually." He said all AI agents will need to make payments to buy or use something, and added that AI agents will eventually far outnumber humans. x402 is an open payments protocol built around HTTP 402, "Payment Required," allowing AI agents to automatically pay for API access or digital services. It mainly supports stablecoin-based onchain payments, enabling agents to pay immediately for needed services without separate accounts or subscriptions.
