Try gxclient-node:getDynamicGlobalProperties

[lanhaoxiang]

curl -XPOST --data '{
    "jsonrpc": "2.0",
    "method": "call",
    "params": [0, "get_dynamic_global_properties", []],
    "id": 1
}' https://node1.gxb.io/rpc

{
    "id": 1,
    "jsonrpc": "2.0",
    "result": {
        "id": "2.1.0",
        "head_block_number": 16639096,
        "head_block_id": "00fde4782b6c91a7723a61e757a1ddbe479b548f",
        "time": "2019-01-24T03:11:06",
        "current_witness": "1.6.47",
        "next_maintenance_time": "2019-01-24T03:40:00",
        "last_budget_time": "2019-01-24T02:40:00",
        "witness_budget": 2774976,
        "accounts_registered_this_interval": 3,
        "recently_missed_count": 0,
        "current_aslot": 16839650,
        "recent_slots_filled": "340282366920938463463374607431768211455",
        "dynamic_flags": 0,
        "last_irreversible_block_num": 16639082
    }
}

head_block_number is the latest block height, and last_irreversible_block_num is latest irreversible block
