ACP discovery document exists

agent_commerce_acp

Checks if Agentic Commerce Protocol (ACP) discovery document is published.

What does this rule check?

ACP enables AI agents to discover your commerce API via /.well-known/acp.json. The discovery document declares protocol name, version, API base URL, supported transports, and available service capabilities.

Why is this important?

Without ACP discovery, agents cannot find your commerce API for automated purchasing, inventory checks, or order management. ACP standardizes commerce interactions for the agentic web.

How to fix

Serve /.well-known/acp.json with protocol.name, protocol.version, api_base_url, supported transports, and capabilities.services.

Examples

GET /.well-known/acp.json

HTTP/1.1 404 Not Found

GET /.well-known/acp.json

HTTP/1.1 200 OK
Content-Type: application/json

{"protocol": {"name": "acp", "version": "1.0"}, "api_base_url": "/api", "capabilities": {"services": ["checkout", "inventory"]}}
