Is there a way to request the date of last transaction via API? I run a request to see balance of my addresses and need to request the date of the last transaction, how would I do that?
If you call the address API i.e.
https://blockchain.info/address/$hash_160?format=json you will get a list of transactions.
They all have a time attribute which is the time in unix format. https://en.wikipedia.org/wiki/Unix_time
