Understanding SP-API Metered and Unmetered Calls
When using Amazon's Selling Partner API (SP-API), your API calls fall into two categories: metered and unmetered. Understanding the difference is important for managing your API usage costs.
Metered calls are API requests that are tracked and counted for billing purposes, meaning they count toward your monthly API usage limits and will be subject to usage fees starting April 30, 2026.
Unmetered calls, on the other hand, are API requests that do not count toward your monthly usage or billing. These calls are free to use and are excluded from all fee calculations. These exclusions are designed to provide developers with flexibility and reduce unnecessary billing.
Below is an exclusion list of Unmetered GET Calls. Developers are encouraged to review this document to understand exactly which API calls will not contribute to their monthly usage calculations and potential overage fees.
