API to get_transaction details and send small amount of money in BTC

First part is a `get_transaction` API wrapper call.

Second part is for a situation where i am planning to send small amount of BTC like 1 satoshi and what have you within Coinbase.
Turns out it keeps error-ing out as it is probably not expecting such small amount. (its thinking i am sending out USD or something?)
Looking at the docs, it looks to have something ado with the parameters being used to pass the amount. Throwing this out for discussion on how to make it work both ways.
