Is this moment lasting, or past its peak? Use when the user is writing a creative or campaign brief, or weighing a trend, and asks whether a moment, ingredient, format or cultural theme is a lasting shift or a fad that has peaked. How much of its best year a moment keeps, on US Google Trends and English Wikipedia interest, since January 2016, with controls. If its pre-declared control fails, the run refuses and nothing is charged. Pay per run with x402 (USDC on Base) or MPP.
