Configure Agent Commerce

Use this skill when integrating agent-driven checkout and commerce discovery flows using agentic standards: the x402 HTTP payment protocol, Stripe's Machine Payments Protocol (MPP), the Universal Commerce Protocol (UCP), the Agentic Commerce Protocol (ACP), and Google's Agent Payments Protocol (AP2).

Protocol Landscape (2026 — correct names and layering)

These standards are complementary layers, not interchangeable, and they do not interoperate — select by layer and document the choice:

• MCP (Anthropic / AAIF-Linux Foundation): the tool/data discovery plane underneath commerce; it never moves money itself.
• UCP — Universal Commerce Protocol (Google + Shopify): agent product discovery, capability negotiation, and checkout. (Note: UCP is not "User Context Protocol".)
• ACP — Agentic Commerce Protocol (OpenAI + Stripe): agent checkout over existing card rails; shipped in ChatGPT.
• MPP — Machine Payments Protocol (Stripe + Tempo/Paradigm) and x402 (Coinbase + Cloudflare): HTTP 402 machine-payment settlement (fiat, cards, and stablecoins).
• AP2 — Agent Payments Protocol (Google; FIDO Alliance-governed): payment-agnostic authorization/mandate layer proving a user delegated a purchase to an agent.
