Coinbase launches open source payment protocol x402 based on HTTP

Coinbase developer platform announced the launch of a new open source payment protocol x402, which aims to activate the Internet to retain the HTTP 402 status code "Payment Required" that has not been enabled for a long time, and transform it into a real online payment layer, suitable for new scenarios such as API service providers, content creators, and context protocols. X402 allows the server to request payment, and the client (including humans and intelligent agents) responds instantly. It supports micro payment pay per use without the need for cumbersome subscriptions. Coinbase stated that the protocol is expected to simplify the Web3 payment process and provide new infrastructure for proxy economy and on chain services. Currently, x402 is open source and developers are welcome to participate in co construction.
