Hi,
I believe it is a duplicate of the other topic you've posted:
viewtopic.php?f=9&t=50900&p=186470#p186470
As I've mentioned there we do not have a public API for HighchartsGPT for now.
I suggest you use ChatGPT API if you want to send requests from your app. You should be able to ask ChatGPT to provide you with a Highcharts config for a chart based on the user prompt.
Best regards!
