## What it is
Agent Payments Protocol (AP2) is an open protocol and Python SDK for secure, interoperable payments initiated by AI agents, addressing authorization, authenticity, and accountability in agentic commerce. The repository provides the SDK, protocol specification, and runnable demo scenarios in Python, Go, and Android.

## Use cases
- let ai agents make purchases securely
- implement agent-initiated payments in my app
- add verifiable user authorization for agent purchases
- build an agentic commerce checkout flow
- integrate payments into an a2a multi-agent system
- prototype agent shopping scenarios without real money movement

## When to choose
- you are building AI agents that initiate or facilitate payments
- you need a standard, auditable protocol for agent commerce across merchants and PSPs
- you want reference implementations and an SDK to extend with new payment methods

## When to avoid
- you need production payment processing today - samples mock payment providers
- your project has nothing to do with AI agents or commerce
- you need a finished MCP server or SDK for a framework other than Python
