Create a datadog screenboard from a timeboard

time-screen.sh

#!/usr/bin/env bash
#params
#dd_api_key=
#dd_app_key=
#dash_id=
curl -sX GET "https://app.datadoghq.com/api/v1/dash/${dash_id}?api_key=${dd_api_key}&application_key=${dd_app_key}" \
 | jq '{
         board_title: .dash.title,
         description: .dash.description,
         template_variables: .dash.template_variables,
         widgets: [.dash.graphs[] | { type: .definition.viz, tile_def: .definition, title: true, title_text: .title, autoscale: true, x: 0, y: 0 }]
       }' \
 | curl -H "Content-type: application/json" -d @- \
     "https://app.datadoghq.com/api/v1/screen?api_key=${dd_api_key}&application_key=${dd_app_key}"

Here is an updated script for the current API:

#!/usr/bin/env bash
#params
dd_api_key=<dd_api_key>
dd_app_key=<dd_app_key>
dash_id=<dash_id>
curl -sX GET "https://api.datadoghq.eu/api/v1/dashboard/${dash_id}?api_key=${dd_api_key}&application_key=${dd_app_key}" \
 | jq '{
         layout_type: "free",
         title: .title,
         description: .description,
         template_variables: .template_variables,
         widgets: [.widgets[] | { id: .id, definition: .definition, layout: { height: 10, width: 10, x: 0, y: 0 }}]
       }' \
 | curl -X POST -H "Content-type: application/json" -d @- \
    "https://api.datadoghq.eu/api/v1/dashboard?api_key=${dd_api_key}&application_key=${dd_app_key}"

It doesn't support groups as free form dashboard don't have groups, so either you'll have to remove them from the original dashboard or extend this to validate if .widget[i].type != groups.
