Everything you need to know about the Estimated Sales API.
Our sales estimation algorithm achieves approximately 95% accuracy for most product categories by analyzing a combination of real-time sales rank data, historical rank-to-sales correlations, category-specific demand curves, and marketplace dynamics. The accuracy may vary slightly for extremely niche categories or newly listed products with limited data history. We continuously refine our models to improve precision across all segments.
The Estimated Sales API supports all 23 Amazon marketplaces globally, including the United States (ATVPDKIKX0DER), United Kingdom (A1F83G8C2ARO7P), Germany (A1PA6795UKMFR9), France (A13V1IB3VIYZZH), Italy (APJ6JRA9NG5V4), Spain (A1RKKUPIHCS9HS), Canada (A2EUQ1WTGCTBG2), Japan (A1VC38T7YXB528), and more. Refer to our documentation for the complete list of supported marketplace IDs.
Sales rank (Best Sellers Rank / BSR) is Amazon's relative ranking of a product within its category based on recent sales velocity. Estimated monthly sales is our calculated projection of the actual number of units sold per month. While sales rank tells you how a product compares to others in its category, estimated sales provides a concrete unit volume figure that can be used for revenue projections, inventory planning, and market sizing. Our API provides both metrics in a single response.
Yes. While each API call processes a single ASIN, you can make concurrent requests to estimate sales for large product catalogs efficiently. Our infrastructure supports high-throughput workloads, and enterprise plans include elevated rate limits for bulk processing. For extremely large-scale operations, contact our team to discuss dedicated capacity options.
Our sales estimation models are continuously updated with the latest marketplace data. When you make an API call, the estimated monthly sales figure reflects the most current sales rank and demand signals available. For products with high sales velocity, data freshness is typically within hours. We recommend querying periodically for products you actively track to capture demand fluctuations and seasonal trends.
