Hi,
I'm sorry but I don't understand the question.
To load THIS vendor you need to use the HikaMarket vendor class and the get function.
To get a list of vendors ; you need to perform a SQL query directly ; there is no function for the listing with specific filters, so best is to do it yourself in the plugin.
