What is x402 and How Does It Work?

In today’s digital landscape, where online transactions are integral to everyday life, protocols like x402 are emerging as solutions for specific payment challenges. Developed by Coinbase in May, this open-source protocol aims to streamline payments using HTTP, a fundamental web protocol. By reintroducing the 402 status code (Payment Required), x402 facilitates programmatic payments without requiring users to sign in or manage complex processes like traditional methods.
