/item_sales/search -- Insufficient permissions to fulfill the request

[vip_1931]

I am testing the method "/item_sales/search" from the "Marketplace-Insights API",

I get is the message:

{
"errors": [
{
"errorId": 1100,
"domain": "ACCESS",
"category": "REQUEST",
"message": "Access denied",
"longMessage": "Insufficient permissions to fulfill the request."
}
]
}

What is that we are missing here?
