No, Amazon's Product Advertising API and Advertising API don’t provide detailed PPC keyword data by ASIN like search volume, keyword ranking, or suggested bids. These APIs only let you manage your own campaigns or get basic product info.

The tools you're using get this data by scraping Amazon, analyzing search results, and using third-party data sources — not from Amazon’s official APIs.

So, to access those detailed keyword insights, you'll need to keep using third-party tools like Helium 10, Jungle Scout, or similar platforms.
