I must be lost then. The python code is an implementation of a program that uses the Coinbase API to make trades, fetch market data, etc. In my day, we'd call that a Program, Library or an SDK. Definitely wouldn't call that an "Unofficial API". When I think of "Unofficial API", I think of an API that wasn't intended for public use and is undocumented and supported by the company. Like the Pandora API some music playe…
Coinbase may have an official API, doesn't mean they support the Python implementation of their API, hence the 'unofficial' as in 'not maintained by the coinbase dev team' These implementations are there for devs to save time and simply import the API implementation as a module and use already made functions to do the API calls
The Coinbase team, to my knowledge, doesn't maintain any implementation... making all implementations "Unofficial" in that sense.
I still fail to see how this python code is considered an "Unofficial API".
