Request body

brand_filterobject

A filter expression for your brand's visibility, mirroring the "Your brand" filter. brand_name matches whether a response mentions your brand: "mentioned" or "not_mentioned". page_status matches how the AI used your pages: "cited" (the AI retrieved pages from your site and referenced them in the answer), "found_but_not_cited" (the AI retrieved pages from your site as potential sources but did not reference them in the final answer), or "not_found" (the AI did not retrieve any pages from your site).
