How to validate Account Balance Retrieval?

cryptoID offers a great service when it comes to investigating history balances for different coins.

Validate an address with many transactions

Consider this public address DCzmzkMBqEz2tLn47W9YuNAV9cFzuWCydW. As of 05. September, 2020 this address contains 399195 transactions. Fairly a lot.

The following curl command may take several seconds

curl -X POST -H 'Content-Type: application/json' -d '{ "network_identifier": { "blockchain": "dgb", "network": "mainnet" }, "account_identifier": { "address": "DCzmzkMBqEz2tLn47W9YuNAV9cFzuWCydW" }}' https://127.0.0.1:8080/account/balance

and yields this output:

{
    "block_identifier": {
        "index": 11489180,
        "hash": "00000000000000000915d818baeeb9cffb3e497e776cddb3a7045186d06731ca"
    },
    "balances": [
        {
            "value": "463275000",
            "currency": {
                "symbol": "DGB",
                "decimals": 8
            }
        }
    ]
}

which can be validated by looking at this url: History Balances

Even after a block reorg (which occur several times a day) the balance remains correct. By specifiying a block identifier in the request, history balances can be easily retrieved.
