API calls for AOS_Products come back as Bad Request

I am writing a bridge/add on and was trying to make an API call to the Products module in Postman to see the exact response, using the url:
https://{domain}/legacy/Api/V8/module/AOS_Products

But what I get back is this

I tried other modules with this exact url and they work fine, so now I’m out of ideas. Any suggestions?

Hello Dimitris,

that one:
/legacy/Api/V8/module/AOS_Products
looks good, the same endpoint which is working here.

Which user do you use for the integration?
Is the access maybe denied by its role?
