Coinbase is expanding its infrastructure for autonomous AI agents, allowing businesses to accept stablecoin payments directly from software systems through its x402 payment standard. The company announced the expansion on Thursday, July 23, alongside new AI trading tools and a developer kit designed for agent-powered applications.
The move reflects Coinbase’s effort to build what the company describes as an “agentic economy,” where AI agents can make payments, manage finances and complete other tasks on behalf of users. Coinbase Business users can now accept USDC payments from AI agents using the x402 standard, which was first introduced in May 2025 to enable stablecoin payments over HTTP for AI agents, applications and APIs.
Last month, agent-generated traffic surpassed human traffic on Base documentation pages for the first time, a milestone Coinbase cited as evidence of growing adoption of agent-based systems. Base is Coinbase’s documentation platform.
Trading Tools and Developer Kit
Coinbase released AI trading tools that allow users to monitor orders, access live market data, and execute actions based on predefined conditions. A software development kit is also available for developers building agent-powered applications on the platform.
The x402 payment standard was designed to remove what Coinbase characterizes as a foundational assumption of the internet’s financial infrastructure. According to the company, the existing system relies on “one assumption: a human clicking the button.” The standard enables automated payments without that human intervention step.
Multiple exchanges and payment companies are positioning stablecoins and blockchain-based payments as infrastructure for AI agents, according to Coinbase. The company did not name specific competitors or provide details on pricing, fees, or transaction limits for USDC payments from AI agents.
