Simply Receive Data from Web Server without Database?

I have a Raspberry Pi Pico W with a temperature sensor, hosting a web server that returns its data in a JSON format whenever requested. How would I make a data source that ONLY receives this data and parses it as JSON to be graphed? I don’t have nor do I need a fancy database or an API, I just want Grafana to receive this data. Nothing else.

(idk if this helps but I am hosting Grafana locally on a Raspberry Pi 4)

You can use infinity plugin which has one feature that takes in web rest api
