On 6 May 2025 Coinbase Developer Platform published x402. Servers return HTTP 402 with payment requirements; clients retry with a signed payment, typically USDC on cheap L2s such as Base. The announcement explicitly targets APIs, apps and AI agents. Documentation and a reference implementation were pointed at x402.org and GitHub.
