API of real-time financial market stock values

Do you know how to introduce an API of real-time financial market stock values ​​into kodular, returned in JSON format?

do you have any api?

else visit here

https://www.google.com/search?client=firefox-b-d&q=API+of+real-time+financial+market+stock+values

I only have this one: https://www.mercadobitcoin.net/api/BTC/ticker/

This returns only the BITCOIN MARKET values.

I would like an API that returns the value of stocks and currencies.

if the site offers such thing then contact the site owner

above site says this error to me
