Amazon Trends API

Amazon product search demand over time, structured as JSON. Track how consumer interest in any product, category, or brand has moved on Amazon - weekly series, growth percentages, and live bestseller rankings via a single POST endpoint.

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.

Common questions

Amazon's Product Advertising API returns product listings and pricing. It does not expose keyword-level search demand as a normalized time series. Trends MCP provides that signal for any product keyword.
Product names or categories work well. Examples: 'air fryer', 'standing desk', 'protein powder'. The signal reflects Amazon search demand for that term.
Yes. Use mode: 'top_trends' with type: 'Amazon Best Sellers Top Rated' to get live rankings.
