Is there an API to have the data in the "overview" section?

[posta246]

Hi,
(sorry for my bad english) is there an API that return the two lines of data shown in the "overview" (the total amount and the %)?
I would like to make a daily linux bash script that:

1. using the API (with the token?), obtain the data
2. send data via telegram message to my private channel

(I know how to do the step 2).
Thanks for any suggestions!!!
If needed, I might share the final script (you have to config a telegram bot/channel before).
