$140 billion FinTech giant Stripe quietly dropped the new machine payments preview. And the most revealing thing about it isn’t the crypto. It’s the status code.

HTTP 402 - ”Payment Required” - has been sitting dormant in the web’s architecture since 1997, reserved for a future where the internet would need native payment rails. Stripe, integrating the x402 protocol developed by Coinbase, just activated it.

The system lets AI agents pay for API calls, compute, and data using USDC on Base, settling in seconds for as little as $0.01 per request. No account, no API key, no human in the loop 🤖

An agent hits an endpoint, gets a 402 response with a crypto deposit address, pays from its wallet, and retries. Done ✅

Here’s why it could be huge and what’s next 👇
