Hello.
We are a company that created a marketing support system in online stores. The module uses artificial intelligence to conduct effective marketing campaigns in social media and search engines on behalf of online stores.
We are interested in placing our module in the Zen Cart marketplace. Therefore, we have a few questions:
1. Does Zen Cart have a marketplace from which plugins for additional tools / extensions for a given platform can be downloaded with or without payment?
2. Are there only plugins for own tools / extensions on marketplaces or also plugins for tools / extensions of external suppliers?
3. On what commercial terms is our module introduced to the Zen Cart marketplace (both free and paid plugins).
4. Where can I find the list of categories of available plugins?

Thank you in advance for your answer.
