## What it is
The Agentic Commerce Protocol (ACP) is an open specification, maintained by OpenAI and Stripe, defining how AI agents, buyers, and businesses interact to complete purchases programmatically. The repository hosts the RFCs, versioned OpenAPI and JSON Schema specs, examples, and changelogs for implementing agent-facing checkout endpoints.

## Use cases
- let AI agents like ChatGPT check out from my store
- implement agentic checkout endpoints for my commerce backend
- accept purchases made through AI shopping agents
- relay payment credentials securely from an AI agent to a seller
- publish my checkout API as MCP or REST for agents
- sell products programmatically without being merchant of record
- integrate agentic commerce with my existing payment processor

## When to avoid
- you need a ready-made shopping cart or storefront application rather than a protocol specification
- your commerce flows are purely human-driven with no AI agent involvement
- you require a fully stable, production-hardened standard - ACP is still in beta with evolving spec versions
