It's clear like water you never used MtGox a single time. Every guy having an account in, knew MtGox is gone years ago! You are 3 or 4 years late man! Even people not having an account know it, it was a drama all over the news. In case it was true you have an account if you were really facing problem to access the site, you would have searched in any search engine some news. You surely were not even trying to log in MtGox, you were looking to post something useless
It is not uncommon for their website to be down while customers will still have full functionality via API.
Didn't know it is possible. How access account via API can be done?
EDIT: Is it this? https://developers.coinbase.com/docs/wallet/guides/send-receive
You use this in a Terminal?
