Amazon made some changes recently. They are mentioned here.

Basically, if your Amazon account doesn't generate any sales using the Amazon Product Advertising API for 30 days, the API will temporarily get disabled on your account.

If this happens, you can use other product linking tools, such as Site Stripe. You will regain access to Product Advertising API once your account again begins to drive referring sales.
