Does Shopify charge application plugin service providers?

Hello, we are a company specialising in digital human live streaming services. We would like to become an application plugin provider on Shopify, and plan to use APIs to technically dock with digital human live streaming technology. Could you please inform us about how Shopify charges for this kind of technical docking? Could you introduce the relevant fee standards and what materials we need to provide in order to successfully interface with Shopify’s API?

If we plan to sell our application on the Shopify App Store and Shopify takes a commission on sales, how much in US dollars does Shopify charge for application plugin access?
