What is the KYAPay Protocol?

1 min read Updated

KYAPay (Know Your Agent Pay) is an emerging protocol combining agent identity verification with payment processing, enabling merchants to authenticate AI agents and process payments with appropriate trust.

WHY IT MATTERS

When humans shop, merchants verify identity through logins and cards. Agents can't do this. KYAPay bridges the gap with standardized agent buyer authentication.

It addresses trust: how does a merchant know the agent is authorized? KYAPay uses identity verification, spending authorization proofs, and payment attestations.

Foundational for agent commerce — without standardized checkout, every interaction needs custom integration.

HOW POLICYLAYER USES THIS

PolicyLayer integrates with KYAPay to enforce spending rules at checkout — validating amount, merchant category, and frequency before completion.

FREQUENTLY ASKED QUESTIONS

How does KYAPay verify identity?
Agent attestations, wallet signatures, and operator-issued credentials proving authorization.
Widely adopted?
Still emerging, growing alongside agent commerce, particularly among merchants wanting risk-controlled agent payments.
Separate account needed?
No — works with existing wallet and identity credentials. Protocol layer, not account system.
