coinbase x402 ecosystem / 2026-05-16
This radar reads public Coinbase x402 pull requests and separates partner listings, MCP payment endpoints, mainnet rails, discovery metadata, and browser/payment-header launch signals. The useful question is not whether a launch mentions x402. It is whether agents can discover the paid surface, understand the cap, receive a proper 402, and reconcile the receipt.
