GateChex – Instantly Know What You’re Gated In on Amazon
GateChex is the ultimate Chrome extension for Amazon sellers to instantly discover which ASINs and brands you’re authorized to sell—no more manual clicks!
With GateChex, you can:
- Instantly see which ASINs you're restricted from selling
- Know which ASINs offer the option to apply for ungating—right from the extension
- Quickly identify gated brands for potential wholesale or direct brand opportunities
**OAuth-Secured SP-API Access**
We use Amazon’s OAuth 2.0 flow and call the Marketplace Participations & Listing Restrictions endpoints in real time—no screen-scraping, no third-party gating logic. Keepa is used only to fetch ASIN lookup and price-history charts—not for gating decisions.
No more guessing, no more wasted time. GateChex empowers you to focus on profitable, unrestricted products and streamline your product research like never before.
How It Works
- Step 1: Connect your seller account via Amazon OAuth 2.0.
- Step 2: Extracts the ASIN from the product page you’re viewing.
- Step 3: Calls Amazon SP-API to retrieve seller marketplace participations and listing restrictions
- Step 4: Present “Gated”, “Apply”, or “Clear” status based on Amazon SP-API data
Install GateChex today and unlock your selling potential.
