Timetable API

[Plus1XP]

Sorry to create an issue, I have a question and had no way to message you.
I have made a program to scrape the f1 timetable and generate an ical.
I'd like to change it to using an API but I can't seem to find what API they are using.
Since you seem familiar with their API's I thought maybe you could point me in the right direction?
if I use https://api.formula1.com/v1/event-tracker, I only get the results of the current race and im not sure what they are using for the request.

Thanks
