ledger_entry
Attention
Price Oracle functionality is part of the proposed XLS-47d extension to the XRP Ledger protocol. You can use these functions on test networks for now. Until there is an amendment in a stable release, the details documented on these pages are subject to change.
You can use the existing ledger_entry
method to retrieve an Oracle
instance.
