What is x402?
x402 is an internet-native payments protocol incubated by the Coinbase Development Platform team. It allows any web service to charge for access to its APIs and content without requiring users to create accounts or manage subscriptions. Connect your agent to paid resources, build new ways to monetize your APIs, and discover new services on x402.
