Affiliates & API – Can I do this?

Hello help forums,

I am not really sure if this is something I can do, but I am going to try and describe what I want and see if it is possible.

I run a book blog
I am an affiliate with multiple programs for buying books, ebooks, and audiobooks.
I utilize Amazon OneLink, if you are familiar with that at all.
I have a vague inkling that this might have something to do with API, but I don’t understand that side of things AT ALL.

What I am looking to do is have a page of new releases, and have people able to see what the price for the book is on my various affiliate sites and choose where they want to buy it.

Another layer to add to this is that especially with ebooks, localization matters. So I would really love if this page would either see where the person is browsing from, or allow them to choose where they are browsing from before viewing. This way they see the accurate pricing for the books.

I have about a half dozen different affiliate accounts, not including all the different Amazons (Canada, US, UK, etc) and all the different book categories (physical book, ebook, audiobook). I don’t want this to be a bulky page, but I feel like if I can show people the prices at various places rather than just buttons, they might be more likely to buy from me.

Thanks in advance!
