@getcolter/cli

Check if any online store works with AI shopping agents.

Colter tests both major agent commerce protocols in one command:

• UCP (Universal Commerce Protocol) — product discovery, browsing, and purchase. Used by Gemini, AI Mode, Copilot, and others.
• ACP (Agent Commerce Protocol) — checkout and payment. Used by ChatGPT, Operator, and others.

Produces Evidence Packs: portable, redacted, replayable records of every verification.

Install
