jsonrpc: string
example: "2.0"

result: string
example: "767969"

}

Get balance for address. Also available through a GraphQL 'addresses' query. If the balance hasn't been updated in a long time, we will double check with the node to fetch the absolute latest balance. This will not be reflected in the current request, but once it is updated, subsequent requests will show the updated balance. If you want to know whether or not we are checking for another balance, use the `balancemulti` action. That contains a property called `stale` that will let you know to recheck that balance in the near future.

Example Value

Get balance for multiple addresses. Also available through a GraphQL 'addresses' query. If the balance hasn't been updated in a long time, we will double check with the node to fetch the absolute latest balance. This will not be reflected in the current request, but once it is updated, subsequent requests will show the updated balance. You can know that this is taking place via the `stale` attribute, which is set to `true` if a new balance is being fetched.
