Short answer

Know Your Agent (KYA) is the practice of verifying an AI agent's identity, operator, and permissions before allowing it to browse, transact, or access data. It is modeled on Know Your Customer checks in financial services. KYA helps merchants and platforms distinguish legitimate agents acting for real users from fraudulent or malicious bots.
