What AI answer engines say a business's phone, address and hours are (?domain=). Businesses on an active licence are asked once a day: Gemini with Google Search grounding (with the sources it cites) and three open-weights models answering from training with no search. Each answer is compared with the business's own record: phone matches / wrong / not_stated; address matches / wrong_street / street_on_service_area_business / city_only / not_stated; hours matches / differs / not_stated / not_compared; says_closed. Wrong values are matched against what each directory prints (printed_by). An engine that errors is unmeasured. The licence holder also gets the history. Signed (crawlcheck-business-ai-answers).
