Agentic Commerce Protocol (ACP)
Agentic commerce and agentic transactions for the agentic economy
Overview
Agentic Commerce Protocol (ACP) defines standards for AI agents to conduct commerce autonomously. Originary integrates with ACP to provide verifiable receipts for agent transactions, ensuring trust and auditability in automated commerce workflows.
When agents execute purchase flows, service bookings, or payment transactions via ACP, Originary issues PEAC-Receipts that prove transaction completion and can be verified by merchants, platforms, and auditors.
Getting Started with ACP
Integrating Agentic Commerce Protocol into your commerce platform enables AI agents to conduct fully autonomous transactions. The protocol standardizes how agents discover products, negotiate terms, execute payments, and receive verifiable proof of purchase - all without human intervention.
Start by exposing your product catalog in ACP-compatible format. Agents can then browse offerings, compare prices, and initiate purchase flows programmatically. When an agent completes a purchase, Originary issues a PEAC-Receipt containing cryptographic proof of the transaction, payment details, and fulfillment status.
For commerce platforms, ACP integration provides immediate benefits: reduced fraud through cryptographic verification, automated reconciliation with machine-readable receipts, and expanded market reach to the growing ecosystem of autonomous AI agents. The protocol works with existing payment rails and can be gradually rolled out alongside traditional checkout flows.
Use Cases
Agent Purchasing
AI agents autonomously purchase goods and services with verifiable transaction receipts for reconciliation and compliance.
Service Booking
Agents book appointments, reservations, and services with cryptographic proof of booking completion.
Payment Verification
Merchants verify agent payment receipts before fulfilling orders, reducing fraud and chargebacks.
Implementation
ACP Transaction with PEAC-Receipt
POST /acp/purchase HTTP/1.1
Host: merchant.example.com
Content-Type: application/json
{
"item_id": "prod_123",
"quantity": 1,
"agent_id": "agent-xyz",
"receipt": "eyJhbGc...PEAC-Receipt-signature"
}Merchants can verify the attached PEAC-Receipt to confirm payment authorization before fulfilling the order.
Benefits for Commerce Platforms
- Reduce fraud with cryptographic payment verification
