Trust and Identity Framework for AI Agents
AgentFi provides a specialized compliance and verification layer that enables AI agents to securely perform actions on behalf of users while allowing third-party websites to verify agent legitimacy. This framework utilizes Know Your Agent (KYA) credentials, the Visa Trusted Agent Protocol (TAP), and Mastercard Agent Pay to establish verifiable identities, secure tokenized payments, and cryptographic signatures. These standards ensure agents can navigate firewalls and complete transactions using RFC 9421 HTTP message signing.
What is agent trust and identity?
Agent trust and identity is a dedicated compliance infrastructure providing the verification, signatures, and credentials necessary for the agentic economy.
* Enables agents to act as authorized proxies for users.
* Provides a mechanism for websites to identify and trust incoming agents.
* Integrates cryptographic proof with financial network standards.
* Establishes a "compliance layer" between autonomous agents and web services.
What is Know Your Agent (KYA)?
Know Your Agent (KYA) is an identity standard designed to provide AI agents with verifiable credentials through rigorous auditing.
* Establishes verifiable identity for autonomous software entities.
* Includes comprehensive agent audits to ensure safety and compliance.
* Issues formal KYA credentials upon successful verification.
* Facilitates trust between agents, users, and service providers.
How does the Visa Trusted Agent Protocol (TAP) work?
The Visa TAP credential enables agents to prove their legitimacy to security firewalls and merchants without compromising the end-user experience.
* Communicates agent legitimacy directly to merchant systems.
* Prevents agents from being blocked by automated security firewalls.
* Maintains seamless transaction flows for automated purchases.
* Integrates agentic identity directly into the Visa payment network.
How are agentic payments and signatures secured?
As of 2025, emerging standards from major financial networks and technical bodies provide the foundation for secure agent-led commerce and message integrity.
Mastercard Agent Pay
Mastercard Agent Pay focuses on network-level payment solutions specifically for autonomous agents.
* Issues agent-specific tokenized cards.
* Enforces granular spending limits for autonomous transactions.
* Generates detailed audit trails for every agent-led purchase.
HTTP Message Signatures (RFC 9421)
The framework utilizes RFC 9421 for the cryptographic signing of agent requests.
* Ensures the integrity of HTTP messages sent by agents.
* Provides a standardized method for servers to verify agent signatures.
* Protects against message tampering during transit.
* Standardizes agent-to-server communication protocols.
