Who actually supports which AI-agent payment protocol?
I mapped 164 companies across 7 protocols: x402, MPP, ACP, UCP, AP2, Visa TAP and Mastercard Agent Pay. Every dot links to its source. 🧵👇

7 agent payment protocols. Great map & information packed newsletter from @wizedaddy123 🤝!
Most of these aren’t competing. Card rails authorize, checkout protocols structure the order, and x402 settles the stablecoin payment.
That last step is where PayAI lives.
