    "time": "1542258543"
}

result:

{
    "body": "Test Data #6",
    "time": "1542440938",
    "previousBlockHash": "a36dc07d7027a14726503116cffa3062976bc3735eddbc49593dd9ca39543348",
    "height": 6,

}

also to get a block:

get request: localhost:8000/api/block/5 and result:

{
    "body": "Test Data #5",
    "time": "1542440935",
    "previousBlockHash": "747d311d967ca3748aec4fc5d90a0c3164d89514e40ef524ad845d44c1db12d8",
    "height": 5,
