I have successfully integrated the Amazon.fr in my react app because I had the keys for PA API Amazon.fr but I want to create a comparison site by adding more EU countries in the app, to do it I need the access and secret keys of other market places, I have applied for the associate accounts but when applying for keys they arr saying this:

Is there any solution to get the keys without sales or any other amazon web api service that I can use to create a search engine with all EU countries?
