Basic Usage

Create an API client:

{ok, Coinbase} = coinbase_api:connect(
    <<"Api Key">>,
    <<"Api Secret">>,
    <<"Api Passphrase">>
).

List exchange accounts:

coinbase_api:list_accounts(Coinbase).

    {ok,[{coinbase_account,<<"Account UUID">>,
                       <<"BTC">>,
                       {decimal,1947978100000000,16},
                       {decimal,0,16},
                       {decimal,1947978100000000,16},
                       <<"Profile UUID">>},
     {coinbase_account,<<"Account UUID">>,
                       <<"USD">>,
                       {decimal,3242303754453185000,16},
                       {decimal,0,16},
                       {decimal,3242303754453185000,16},
                       <<"Profile UUID">>},
     {coinbase_account,<<"Account UUID">>,
                       <<"ETH">>,
                       {decimal,0,16},
                       {decimal,0,16},
                       {decimal,0,16},
                       <<"Profile UUID">>}]}
