Protocol

AP2 (Agent Payments Protocol)

A protocol direction for scoped, accountable payments initiated through agentic flows.

Definition

AP2 is a protocol direction for payments in agentic commerce. The core issue is not only payment transport, but how mandate, amount, merchant, credential scope, user permission, and audit evidence are represented.

Why it matters

Payments are the highest-trust boundary in agentic commerce. The protocol layer must preserve user control, payment scope, and merchant accountability.

How HARNEXA uses it

HARNEXA treats AP2 as a future transactional rail. Public pages discuss readiness only; no public HARNEXA page exposes payment execution.

FAQ

Questions this definition answers.

Does HARNEXA run public AP2 payments?

No. Public HARNEXA protocol surfaces are readiness and evidence only.

What must exist before agent payments?

Human approval policy, payment scope, support ownership, legal review, credential handling, audit logs, and AgentOps reporting.
