Coinbase is betting that the next wave of crypto adoption won’t come from humans at all. The exchange has rolled out a system where AI agents autonomously earn and spend credits on research data, tooling, and other vendor services, all settled through its x402 machine-to-machine payments protocol.
The platform, called “Coinbase for Agents,” launched on June 11, 2025, and represents the company’s most ambitious push yet into the intersection of artificial intelligence and blockchain infrastructure. Vendors on the platform provide MCP-native APIs rather than traditional REST endpoints, a technical distinction that fundamentally changes how AI agents discover and interact with services.
What x402 actually does
The protocol enables instant, on-chain micropayments triggered by service requests, settled in USDC on the Base Mainnet. Each transaction costs roughly $0.0001 in fees and settles in under two seconds.
Coinbase originally launched the x402 protocol in May 2025. Since then, it has processed over 100 million transactions. The protocol received V2 upgrades in December 2025 that increased its efficiency, and Coinbase co-founded the x402 Foundation alongside Cloudflare in September 2025 to further develop the standard.
