Colter

Agentic Commerce Verification Toolkit

Colter checks whether online stores are ready for AI shopping agents. It scans for protocol support (ACP, UCP, TAP), runs conformance tests, and generates portable Evidence Packs that prove agent-readiness.

What It Checks

Colter probes three agentic commerce protocols:

Protocol	Ecosystem	Agents
ACP (Agent Commerce Protocol)	OpenAI / Stripe	ChatGPT, Operator
UCP (Universal Commerce Protocol)	Google / Shopify	Gemini, AI Mode, Copilot
TAP (Transaction Agent Protocol)	Visa / Cloudflare	Visa-verified agents

Each protocol has its own .well-known endpoint, manifest format, and conformance requirements. Colter tests all of them.
