- The agent payment protocol war is on: x402, Google's AP2, OpenAI + Stripe's ACP, Meta's new PAP, Visa, Mastercard
- The agent payment protocol war is on. x402, Google's AP2, OpenAI + Stripe's ACP, Meta's new PAP, Visa, Mastercard. All fighting to become how AI agents pay. Agents already pushed 138.5M payments through x402 — 87% under $0.10. One of them wins the rails. Who?
- Why it matters: Multiple competing agent payment protocols — x402, Google's AP2, OpenAI + Stripe's ACP, Meta's new PAP, Visa, and Mastercard — are fighting to become how AI agents pay, and x402 has already processed 138.5M agent payments with 87% under $0.10, so the outcome will determine which rails agent payments run on.

- Why it matters: It frames x402 as the payment rail for AI agents and raises the core Agentic Payment infrastructure question of settlement and delivery verification through an escrow → deliver → challenge → settle loop.
