# Get AI conversion attribution

> Returns AI-referred sessions, GA4 key-event conversions and average engagement time together, split by AI engine and by landing page, for a fixed 7, 28, or 90 day window. Landing pages carry a page-value score: the page's share of the window's AI-referred conversions weighted by its engagement rate. Attribution is directional: sessions and conversions are correlated through the GA4 landing page and session source, never through a per-visitor identity, and an uncovered window reports null rather than zero.
