Payments Stack for AI agents to make autonomous purchases without worrying about compliance.
Three simple steps to enable autonomous agent payments
Use Visa's Agent API to securely tokenize user payment methods with proper consent and verification.
Your agent uses the secure token to pay at any merchant checkout (Stripe, Square, etc.) with built-in spending controls.
You avoid PCI compliance, fraud liability, and complex merchant integrations. We handle the heavy lifting.
Visa and Mastercard just launched agent-first payment infrastructure, enabling secure autonomous transactions for the first time.
AI agents are moving beyond chat into transactional workflows. They need payment capabilities to deliver real value.
Existing payment APIs weren't built for agents. Developers need agent-native solutions that handle consent, limits, and compliance.
