get https://api.chain49.com//v2/tx/
Get transaction returns "normalized" data about transaction, which has the same general structure for all supported coins. It does not return coin specific fields (for example information about Zcash shielded addresses).
A note about the blockTime field:
for already mined transaction (confirmations > 0), the field blockTime contains time of the block
for transactions in mempool (confirmations == 0), the field contains time when the running instance of Blockbook was first time notified about the transaction. This time may be different in different instances of Blockbook.
