API connector, JSON response, Data

Just starting out using API connector. I have setup a call, with type as “Data” to an external source. I first setup a repeating group with the data source configured to call my external api, using the value from an input text field to pass as one of the params required.
All good.
I then wanted to call the API on demand, so I removed the data source from the repeating grid and in response to a button press, I set the display list on the repeating group in a workflow.
THE PROBLEM: The list in the response (“matches”) is what I assigned as a data source to the repeating grid, but how do I get to the data outside of the list in the JSON response? Specifically, the “count” and “more” items below

The Json response looks like this:
{
“q”: “search term”,
“more”: true,
“count”: 8881,
“matches”: [
{
“match”: {
“label”: “songname”,
“image”: “junk.jpg”,
}
“bookmarked:” false,
},
{
“match”: {
“label”: “songname”,
“image”: “junk.jpg”,
}
“bookmarked:” false,
}
