Agentic Commerce Protocol (ACP) Checkout Engine

Implements the full Agentic Commerce Protocol negotiation and checkout state machine so autonomous buyer agents can configure packages, validate rules-based discounts, and complete delegated or human-confirmed transactions.

Executive Summary

Agentic Commerce Protocol (ACP) integration exposes /api/acp/config, /api/acp/negotiate, and /api/acp/checkout endpoints so AI agents can configure line items, request deterministic quotes, and execute authorized settlements.

Deployment Sequence

01. Pricing Rule Codification

Encodes volume tiers, mobilization fees, and bundle rules into deterministic server-side evaluators.

02. Stateful Session Engine

Builds idempotent negotiation and checkout endpoints with strict rate limiting and bearer validation.

03. Settlement Rail Wiring

Connects approved checkout sessions to enterprise ACH, wire instructions, or delegated payment tokens.

Technical Questions & Specifications

Can an agent invent a discount during ACP negotiation?

Never. All pricing math executes inside deterministic server-side rules engines; the language model or external buyer agent only submits structured quantity and scope parameters.

What settlement methods are supported for high-ticket B2B engagements?

High-ticket B2B checkouts default to automated ACH debit and structured wire settlement to eliminate card interchange leakage, while supporting delegated payment tokens for instant self-serve tiers.
