Coinbase Unveils AI-Focused Payment Platform with x402 Protocol

Coinbase has launched a platform called 'Coinbase for Agents' that allows AI agents to autonomously earn and spend credits on research data, tooling, and other vendor services.

The platform uses Coinbase's x402 machine-to-machine payments protocol, which enables instant micropayments settled in USDC on the Base Mainnet. Each transaction costs around $0.0001 in fees and settles in under two seconds.

Since its launch in May 2025, the x402 protocol has processed over 100 million transactions, with a significant increase in efficiency following V2 upgrades in December 2025. The Coinbase for Agents platform represents the company's most ambitious push yet into the intersection of artificial intelligence and blockchain infrastructure.
