How to call a python API/Script and send data to the python API for some NLG analysis

Hi,

I am new to the power BI environment. I have a requirement where I need to call a python API/script from Power BI each time a filter is applied and need to send data to the API to perform some NLG. 

The python API/script will return a sentence or set of sentences which I need to display on the dashboard.

Is this possible to achieve in Power BI and if yes, how do I proceed with it.

Some additional details:
   For eg, if I have created a bar chart for marks details with a filter being for each year, as soon as the filter changes, I want to call the API/script and send the data for that particular year and get back the NLG analysis from the API/script.

Thanking you.

Best regards.
