Marketplaces
No licensed marketplace adapter is connected. A demo provider exists for development and is labeled Demo data. This page does not claim that Amazon, or any other marketplace, can be searched today.
What coverage will require
A live adapter will be added only after the provider's current documentation, access rules, and written permission to store and display the data are confirmed.
Amazon Selling Partner API is not a source of other sellers' unit sales. Sales figures from research providers, if they are licensed later, will be labeled as estimates.
What you can do now
You can review the interface shell. Sample rows elsewhere in the app are demo fixtures, not marketplace observations. The demo provider is not a paid data feed.
