Estimates how often each of 1 to 50 phrases is asked in AI assistants each month, in the priority market, without saving anything. Use it to vet a question before adding it as a buyer question. Results come back in input order; aiSearchVolume is null when the provider has no estimate. This is AI search volume, not the Google search volume research_keywords returns. If this refuses because the workspace is not set up, call get_setup_status and check its rows, including skipped ones. Add a phrase with save_strategy_item (kind buyer_question). Related: refresh_ai_volume, get_ai_visibility, set_up_market.
