Fetching Json data from API

Hi I just want to fetch a standard text output from an API source with a URL, but I can’t see anything in the docs that’s much help, this isn’t ORC based and all the questions about API’s in the forum only seem to be about issues with that.

[GET] https://api.taapi.io/rsi?secret=MY_SECRET&exchange=binance&symbol=BTC/USDT&interval=1h

I simply need someway to store the following kind of result so I can do a source search on it {“value”:48202.687257633756,“valueAdvice”:“long”}

You can search the API response directly in the browser.

Here is a test macro. Since I do not have the API key, I search the JSON response for the word “Please”, which is part of the error message.

      "Value": "",

    },
    {

      "Target": "Please",
      "Value": "a",
      "Description": ""
    },
    {
      "Command": "echo",
      "Target": "${a}",
      "Value": "green",
      "Description": ""
    }
  ]
}
