x402 revives the original “HTTP 402 Payment Required” status code to allow bots, agents, and apps to pay-per-call using stablecoins—no API keys, no human-in-the-loop setup required. Make any API or MCP server accessible to agents without human config.

This is smart — not sure if it's the right solution, but IIRC @bradfitz had been trying to solve for HTTP 402 for years.
Smart for Coinbase to take this on — and provide a payment mechanism for MCP and bot APIs (among other things)!

I've always wondered why this existed, and now I'm excited to see it being worked on.
P.S. @bradfitz is the GOAT.
Seems very odd not to just build this on BTC lightning.

@mikestaub being chain-agnostic was a goal.
Absolutely love this concept! Reviving the HTTP 402 status code for internet-native payments is a game-changer. The idea of enabling bots and agents to pay-per-call using stablecoins without the need for API keys or human intervention is brilliant. Can't wait to see how this evolves!
