Amazon Trends API

Amazon's Product Advertising API is built for affiliate links and product lookups. It returns pricing, availability, and reviews. What it does not return is keyword-level search demand over time - how interest in "air fryer" or "standing desk" has grown or contracted across months and years.

That's the gap Trends MCP fills. Same single endpoint, same JSON structure as every other source.
