@Onda_su_onda:
It's hard to say.
According to the Livecoin API documentation, errorCode 2 means "Livecoin system error".
But they do not provide more information.
Perhaps it was a temporary problem at Livecoin.
Can you please also double check your key and secret is correct and with the right permission.

@zaebumba:
We have updated the LINK prices.

Best,
