How can i request a call to HA and receive a JSON?

Hi,

I have a KNX system with a gira homeserver.
this pulls my solar info from there cloud but has a limited update rate.
As I got a modbus TCP connection with my inverter and HA working I was wondering if i could pull the data locally from HA.
I send this to Solaredge: monitoringapi.solaredge.com/site/1043854/overview.json?api_key=OK9…1

And get this return: {“overview”:{“lastUpdateTime”:“2023-02-12 15:53:44”,“lifeTimeData”:{“energy”:1.3251802E7},“lastYearData”:{“energy”:97630.0},“lastMonthData”:{“energy”:45941.0},“lastDayData”:{“energy”:1244.0},“currentPower”:{“power”:134.07837},“measuredBy”:“INVERTER”}}

Thanks a lot!
Best Regards,
Jo
