Coinbase has announced a major expansion into AI-powered financial services, introducing USDC payment acceptance for businesses via autonomous AI agents. This initiative forms part of a wider effort to enhance the company’s suite of payment, trading, and developer solutions. Coinbase stated that firms using its business platform can now accept USDC transactions from AI agents, leveraging the x402 payment standard. First launched in May 2025, x402 enables automated stablecoin payments over HTTP for AI agents, applications, and APIs. This new system targets the growing demand for seamless financial transactions carried out by artificial intelligence on behalf of users and institutions.
