What first attracted me to Bitcoin and cryptocurrencies was that the Internet lacked a digital money protocol. HTTP is the universal information protocol. When HTTP/1.1 was introduced in 1999, ๐ฐ๐ฌ๐ฎ ๐ฃ๐ฎ๐๐บ๐ฒ๐ป๐ ๐ฅ๐ฒ๐พ๐๐ถ๐ฟ๐ฒ๐ฑ was specified as a standard response. Ahead of its time. Money is information. Fast forward to 2025 and itโs clear that the term โuser agentโ was also foretelling. AI agents will perform tasks on our behalf and in doing so will have to exchange information and transact. x402 is pioneered by @coinbase as an open payment protocol. This is an idea whose time has come. Excited to make it available to our developers using @aisdk and shipping MCP serversโฆ in like 3 lines of code.
