为什么是行动型商业

人工智能代理正从“回答问题”转向“完成任务”，包括浏览产品、比较价格、支付以及代表用户管理订单。这需要新的代理间通信协议、机器可解析的商业标准，以及无需账户、会话或人工干预即可运行的支付轨道。

Why agentic commerce

AI agents are moving from “answer questions” to “get things done,” including browsing products, comparing prices, paying, and managing orders on behalf of users. This requires new protocols for agent-to-agent communication, commerce standards that machines can parse, and payment rails that work without accounts, sessions, or human intervention.

Commerce protocols

How agents interact with merchants: product discovery, cart building, checkout, and order management.

ACP (Agentic Commerce Protocol)

Open standard by OpenAI and Stripe. Powers ChatGPT Instant Checkout; supports 1M+ merchants via Shopify and Etsy. Payment-infrastructure agnostic.

• ACP Documentation - Primary docs on OpenAI’s developer platform.
• ACP GitHub Repository - Specification and implementation (Apache 2.0).
• Stripe ACP Integration - Stripe’s integration guide.
• Stripe Blog: Developing an Open Standard - Technical overview and rationale.

AP2 (Agent Payments Protocol)

Google’s open protocol for payment-agnostic agent-led transactions. Uses Verifiable Digital Credentials (VDCs) and a three-mandate model (Intent, Cart, Payment). Backed by 60+ organizations including Adyen, Mastercard, PayPal, Visa, and Coinbase.
