Interpret the zero-amount bucket in Monero output histograms
An analytics importer may accidentally classify RingCT outputs as worthless when it encounters a daemon histogram bucket with amount zero. That bucket is an encoding category.
Request the RingCT bucket explicitly
Use a local daemon permitting histogram queries. Inspect the row for amount zero and its total_instances. For historical transparent amounts, query those amounts separately in atomic units. POST this example to /json_rpc on monerod.
{
"jsonrpc": "2.0",
"id": "guide",
"method": "get_output_histogram",
"params": {
"amounts": [
0
]
}
}
Report counts without inventing a value
The zero bucket counts confidential-amount outputs. Multiplying its count by zero would incorrectly assign a monetary value to hidden amounts. It is a historical output count; the same output remains part of chain history after a spend. This query cannot determine a wallet's available balance.
