How to get the Block Irreversible status?

Question

I can get the irreversible status of the transaction because transaction information has both last_irreversible_block and block_num to know the status. But how to get this information for Block? Getting Block information returns:

{
  "timestamp": "2021-01-28T17:58:59.500",
  "producer": "inith",
  "confirmed": 0,
  "previous": "02e1c78787ff4d4ce6124831b936bb4ef6015e470868a535f1c6e04f3afed8a1",

  "block_num": 48351112,
  "ref_block_prefix": 3493375603
}

It has block_num but not last_irreversible_block. And What is confirmed? Is it related to irreversible status?

Answer 1

Use /v1/chain/get_info to know the last_irreversible_block_num
