x402 - An open protocol for internet-native payments from Coinbase
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)!
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!

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.
