// Core Protocols

Two Protocols. One Vision.

AI Commerce is built on a dual-protocol architecture — one optimised for autonomous agent transactions, the other for universal human-and-machine interoperability.

⚡

Agentic Commerce Protocol

Purpose-built for AI-to-AI transactions. Agents autonomously discover services, negotiate terms, execute purchases, and settle payments — no human in the loop.

Agent identity & capability advertisement via MCP
Autonomous price negotiation with guardrails
Intent-based purchasing (what, not how)
Real-time settlement with escrow verification
Multi-agent supply chain orchestration
Budget policies & spending limits per agent

🌐

Universal Commerce Protocol

A standard checkout and payment layer for any platform, any device, any actor. Humans, agents, and systems all transact through one unified interface.

Unified checkout schema (JSON-LD + Schema.org)
Multi-PSP settlement (Stripe, PayPal, crypto rails)
Cross-border compliance & tax automation
One-click agent-assisted checkout for humans
Webhook-first event architecture
PCI-DSS compliant tokenised payment flows

How a Transaction Works

From intent to settlement in four steps — agents handle the complexity, protocols ensure the trust.

Discover

Buyer agent broadcasts a purchase intent. Seller agents matching the criteria respond with offers via MCP tool calls.

ACP

Negotiate

Agents autonomously negotiate price, quantity, SLAs, and delivery terms within policy guardrails set by their human operators.

ACP

Checkout

Agreed terms flow into a standardised checkout object. Payment is routed to the optimal PSP with full tax and compliance handling.

UCP

Settle

Funds move through escrow with cryptographic verification. Both agents receive settlement confirmation and update their ledgers.
