Maybe. Whats wrong?

Looks like bc.i does not return any data for some reason. Not sure why. They limit the number of requests for 1 every 10 seconds, but this should not block the 1st response. I honestly dont want to bother with bc.i further.

You could use blocktrail [1] instead, but they require an API key and limit to 2 requests per second (burst) so youd have to include wait states.
