API pricing for a small site with no backend?

Question

API

Good afternoon! There is a small site on 15 pages. Since the dynamic information on the site was only valuable, we decided, for the sake of speed, to do it without any CMS, through a static site generator. Accordingly, there is no backend as such.

There are quite a lot of prices on the pages and now they often change = a lot of manual labor (prices come with a price list in excel format). There are sites for processing price lists that can accept an Excel format and process it, give access via API.
How, given the above, is it better to implement this . I ask you to at least indicate in which direction to dig. I have never worked with API before.

Answer 1

What you need today is called headless cms or headless ecommerce. There are ready-made tools for maintaining goods and providing them through the API. Which tool to choose is up to you, there are already more than zero of them.
