read custom dashboard screen with api

[Firmbyte]

*Zabbix newbie here.

My place of work use Zabbix, with Custom screens, and I'm trying to read the info on them. The custom screen shows processes that are running on server, separated by server. I've been using screen.get and screenitem.get but not getting the information that is displayed on the page.....only getting this type of info, see below. How can I get the actual information that is displayed on the page? it's in text.

screenitemid : 3054
screenid : 226
resourcetype : 11
resourceid : 0
width : 500
height : 50
x : 0
y : 3
colspan : 1
rowspan : 1
elements : 0

halign : 1

screen.get and screenitem.get are APIs that get what settings are done for the screen.
It is not an API to retrieve images and data displayed on the screen.

Problem solved...
$Itemget = @{
jsonrpc = "2.0"
method = "item.get"
params = @{
output = "extend"
itemids = $itemlist
sortfield = "name"
}
auth = $session.result
id = $session.id
} | ConvertTo-Json

Invoke-RestMethod "$site/api_jsonrpc.php" -ContentType "application/json" -Body $itemget -Method Post

I solved the problem using the query below, including 2 functions to convert the lastclock to locatime and another to get the Host name from the hostid.

$Itemget = @{
    jsonrpc = "2.0"
    method = "item.get"
    params = @{
        output = "extend"
        itemids = $itemlist
        sortfield = "name"
    }
    auth = $session.result
    id = $session.id
}  | ConvertTo-Json

$Results = Invoke-RestMethod "$site/api_jsonrpc.php" -ContentType "application/json" -Body $itemget -Method Post
ForEach($item in $Results.result) {
                $output += [PSCustomObject] @{
                    Itemid = $item.itemid ;
                    Host = Get-HostNamefromId($item.hostid) ;
                    Lastclock = Convert-FromUnixdate($item.lastclock) ;
                    Lastvalue = $item.lastvalue ;
                    Prevvalue = $item.Prevvalue ;
                    }
    }
$output
