def getbalance(addr)
  json_get('address', 'balance', addr)['data']['balance']
end

#getblock(number) ⇒ Object

The blockr.io block/txs method appears to omit some transactions. As such, we’ll be using blockchain.info for this query. Ideally, this would work: json_get(‘block’, ‘txs’, number.to_s)[‘txs’]

Raises:

  • (ResponseError)

NOTE: The blockr Api only shows the most recent 200 transactions on an address. Either this method should use the non-API query mode, or an alternate API driver will be needed to properly support this method.

Additionally, this api call returns the block times, but not the relay times A better api would sort these by relay times.
