Agentic Commerce Protocol Documentation (agentic-commerce-protocol.com)

The Agentic Commerce Protocol (ACP) documentation has been published as an open-source, community-designed specification under the Apache 2.0 license, enabling businesses to transact with AI agents and any compatible payment processor. ACP defines an interoperable flow where AI agents act as intermediaries that pass secure payment tokens between buyers and merchants, letting companies surface products to high‑intent buyers through agents while continuing to use their existing commerce stacks. Implementers can integrate ACP to participate in ChatGPT’s Instant Checkout and process payments via Stripe or any ACP‑compatible payment service provider. For the AI/ML community, ACP is significant because it standardizes transactional capabilities for agentic systems, turning conversational agents into commerce-enabled endpoints without forcing app developers to become merchants of record. Technically, the spec emphasizes tokenized payments, agent-buyer-merchant messaging, and compatibility with current payment infrastructures—reducing friction for adoption and enabling new UX patterns (in-app discovery, agent-driven purchases). The open license encourages broad ecosystem participation but also raises operational concerns around security, privacy, and compliance that implementers must address when handling tokens, consent, and settlement.
