}Amazon's Product Advertising API requires approval and a sales threshold, and it does not expose search demand anyway. Seller tools like Helium 10 track listings and rank; Trends API tracks the demand side: how often shoppers search for a product or category, normalized so you can compare it with Google and TikTok demand in the same units.
The cross-platform view matters for product research. A product whose TikTok hashtag volume doubled last quarter but whose Amazon search volume has not moved yet is a different opportunity than one where demand already peaked on both.
Validate demand for a product idea before sourcing inventory.
Spot rising product searches weeks before competition piles in.
Back category recommendations with demand curves, not vibes.
Watch whether Amazon demand for your category is growing or shrinking.
