Ethereum (@ethereum): 3/ HTTP 402 was defined over 30 years ago as “Payment Required,” but never widely used.
Estimated coin impact
Scores are not price-change percentages. High impact means a score of +70 or more, or -70 or less.
3/ HTTP 402 was defined over 30 years ago as “Payment Required,” but never widely used. Now, Ethereum gives it purpose. With x402 and EIP 3009, any server can quote a price in USDC. If the agent pays, the request goes through. If not, it’s denied.
