Understanding Amazon Product Statistics

The Amazon Product Statistics endpoint is a powerful tool for understanding product performance. By retrieving detailed statistics such as sales rank and review counts, you can gauge demand and adjust inventory levels accordingly.

Practical Use Case: Forecasting Demand

Let’s say you want to analyze the demand for a specific product, identified by its ASIN. Here’s how to use the /amazon-product-statistics endpoint:


curl --location --request GET 'https://sellermagnet-api.com/amazon-product-statistics?asin=B08N5WRWNW&marketplaceId=A1PA6795UKMFR9&api_key=YOUR_API_KEY'

The response includes valuable data points like bestSellerRank and salesRankHistory. By monitoring these metrics over time, you can identify trends and forecast future demand.
