… Sadly, I gave up and lost all enthusiasm for it when the Coinbase API turned out to be a load of badly documented and contradictory shit that would always return zero balance when I could login to Coinbase and see that simply wasn't true. I tried a couple of client libraries, and got nowhere with it. The prospect of having to write another REST API client was too much for my current "end of year" patience. What started as a funny weekend project idea was completely derailed by a crappy API. I would be interested to see if anyone else tried this.
