Unable to get data from JSON in Applescript - json

Question

So I'm able to get the values from one api but I'm unable to get the second value, which is a currency conversion rate (from an entirely different source). I've pasted my code below, any help would be much appreciated.
set json to (do shell script "curl https://www.bitstamp.net/api/v2/ticker/xrpusd")
tell application "JSON Helper"
set result to read JSON from json
set price to |last| of result as number
end tell
set json to (do shell script "curl https://api.fixer.io/latest?symbols=INR")
tell application "JSON Helper"
set result to read JSON from json
set inr to |INR| of result as number
end tell
set result_string to "₹" & price * inr & ""

Answer 1

If I open the second URL in a browser, here’s the JSON that gets returned (formatted for easier reading):
{"base":"EUR",
"date":"2018-02-05",
"rates":{
"INR":79.744
}
}
The INR value is inside the rates value. Therefore, you need to reference it like so:
set inr to (INR of rates of result) as number
I don’t see any reason to enclose INR inside vertical bars, as there’s no conflicting AppleScript commands or variables with that name. You can even get away with defining inr as a user-defined variable, and AppleScript will be able to distinguish when you’re referencing that from when your referencing INR of rates.
However, result is a pre-defined AppleScript property, so I would avoid using this in the way that you have. What you can do is change this line:
set result to read JSON from json
to this:
read JSON from json
and keep the subsequent line as it is (with my suggested correction from above). Now you’ll be using the AppleScript result property correctly.
