• ask_arc

  Read whether an AI agent can reach checkout for a brand the ARC Index already lists. Use it for 'is <brand> agent-ready?', 'how does <brand> score on ARC?' or 'which <category> brands do agents get furthest with?'. For any store URL, call precheck first. No login and no new scan. Pass a brand, URL, or category. Returns the score, evidence, and both lanes: the agent-catalog HTTP check and the browser cart. The JSON field `agents_can_buy` is true when the catalog returned a checkout link or a browser shopper added the product to the cart. ARC stops before payment. It is not a completed order. The catalog check does not change the score. A missing score is not a zero. Results are advisory.
