When your AI agent makes a purchase, PSPs ask: "How do we know this came from YOUR agent and not a hacker?"
❌ API Keys
Only prove USER identity, not AGENT identity. Can be stolen/leaked.
❌ OAuth Tokens
Authorizes user actions, but doesn't verify which agent executed them.
✅ Visa TAP
Cryptographic proof of agent identity. Tamper-evident, non-repudiable.
Result: +8 AgentScore points, 15% higher PSP approval odds
