A query that returns the cost of a query prior to submitting the query to network node for processing. If the cost of the query greater than the default max query payment (1 hbar) you can use
setMaxQueryPayment(<hbar>) to change the default.V1
Method | Type | Description |
|---|---|---|
getCost(<client>) | Client | Get the cost of the query in long representation |
getCostAsync(<client, withCost, onError>) | Client, Consumer<long>, Consumer<HederaThrowable> | Get the cost of a query asynchronously |
Java
//Create the query request
AccountBalanceQuery query = new AccountBalanceQuery()
.setAccountId(accountId);
