Can we store live data in store db?

Suppose I want to sell silver coins at the spot price. Because silver prices keep changing. So how to do that? How can I show the spot price to my customers using the Wix store? Which Wix API should I use?

You mean auto update price?
If yes, use http-functions + wix-store API (it should be something for product updates)

Yes. Like the user must be able to purchase on live spot price. Can you guide me?

The product price must be updated automatically to the live spot price by API. I want to use WIX store because it is easy to offer promotional discount through the store. I need help with updating product price with API. Inviting you to guide me.

Sorry for late reply.
