Open Agentic Commerce Protocol

Protocol, trust, policy, artifact authority for agentic commerce.

Grantex is the OACP authority layer. AgenticOrg runs buyer and seller AI agents. Shopify, POS, and merchant systems remain source of record. Pine Labs Plural/P3P, POS, and other provider rails own mandate, payment, and in-store execution.

What Grantex does

Authority

Issues or refuses canonical internal OACP artifacts.

Policy

Defines source, freshness, TTL, revocation, and risk rules.

Verification

Checks issuer, signature metadata, payload hash, scope, and safety.

Adapters

Governs compatibility mappings for client and partner payloads.

Four-party architecture

Merchant and POS systems

Shopify, POS, OMS, inventory, policy, support, and order systems keep operational truth.

AgenticOrg runtime

Seller Commerce Agent onboarding, Shopify sync, buyer sessions, channel bridges, OACP cache, and Offline POS handoff orchestration.

Grantex authority

Trust, policy, canonical OACP artifacts, artifact verification, and protocol adapters.

Provider and POS rails

Pine Labs Plural/P3P, POS, and payment providers own mandate, payment, receipt, and final transaction status.

Artifact families

OACP artifacts carry source, freshness, policy, adapter, and capability evidence.

Protocol adapter support

Adapter	OACP meaning	Boundary
Schema.org	Product and Offer JSON-LD derived from merchant source artifacts.	No source-of-record change.
UCP-style	Capability profile derived from policy and artifact families.	Compatibility mapping only.
ACP-style	Commerce interaction profile for clients.	No checkout creation.
AP2-style	Mandate/payment evidence profile shape.	No mandate or payment execution.
A2A	Agent card and task metadata.	No execution approval.
MCP	Tool metadata for ChatGPT/Claude-style clients.	AgenticOrg runtime still enforces cache and policy.
OpenAPI	Buyer-safe schema for Gemini/Perplexity-style clients.	No private merchant payloads.

Why Grantex is not a toll booth

Grantex signs and verifies authority artifacts. AgenticOrg may answer non-binding buyer questions from valid cached artifacts until TTL, freshness, revocation, or policy state requires refresh.

Payment, POS, and order boundary

Final payment, mandate, checkout, POS confirmation, order, stock hold, refund, return, and shipment execution requires the approved provider, merchant, POS, and channel path. OACP artifacts do not invent success.

Integrate AgenticOrg with Grantex authority

AgenticOrg sends Grantex public-safe authority requests for allowlisted tenants, caches returned OACP artifacts, and exposes buyer surfaces with source and freshness labels.
