¿Is there a problem with Api Finance?

I had until a few days a working simple api to check the price of dollar, euro and canadian dollar.
Today i check it and is not showing anymore, i didnt make any change to my code, i get into the api console test and i see is working, but in my code doesnt work anymore.

Which will be the best way to know if is something wrong with my code (maybe a newly deprecated instruction) or is a yahoo problem?

Thanks in advance for the help.
