Coinbase launches AI agent payment tools as agent traffic surpasses human traffic on Base documentation pages

Coinbase has introduced a suite of payment, trading and developer tools for the emerging AI agent economy. A Coinbase spokesperson told The Block that, starting in June 2026, around 53% of web traffic to the Base blockchain's documentation came from agentic visitors. Coinbase Business is rolling out USDC payment acceptance through the x402 standard, while Coinbase for Agents now supports natural-language conditional trading. A new CDP x402 SDK also enables developers to add agent payment acceptance to an API, MCP server or web service using three lines of code.
