Linux Foundation x402 protocol enables native AI payments

Short summary

The Linux Foundation launched the x402 Foundation to standardize machine-to-machine payments via HTTP, enabling AI agents to pay for services natively without separate billing systems. The protocol originated at Coinbase and uses the long-dormant HTTP 402 status code, supporting both traditional cards and stablecoins. Forty organizations including AWS, Google, Visa, Mastercard, and Stripe have joined the initiative.
