Check for recent price drops on a product
Check whether a product’s current price is below its rolling average within a configurable lookback window. Returns current price vs. the average across the window plus the lowest-seen price and date. Response field avg_price_last_30d is a fixed name for backwards compatibility; the value is always computed across the configured lookback_days window.
