ledger_entry

[Source]

The ledger_entry method returns a single ledger object from the XRP Ledger in its raw format. See [ledger format][] for information on the different types of objects you can retrieve.

Note: There is no commandline version of this method. You can use the json command to access this method from the commandline instead.

Request Format

An example of the request format:

WebSocket

{
  "id": 3,
  "command": "ledger_entry",
  "type": "account_root",
  "account_root": "r9cZA1mLK5R5Am25ArfXFmqgNwjZgnfk59",
  "ledger_index": "validated"
}

JSON-RPC

{
    "method": "ledger_entry",
    "params": [
        {
            "account_root": "r9cZA1mLK5R5Am25ArfXFmqgNwjZgnfk59",
            "ledger_index": "validated",
            "type": "account_root"
        }
    ]
}

This method can retrieve several different types of data. You can select which type of item to retrieve by passing the appropriate parameters. Specifically, you should provide exactly one of the following fields:

  1. index - Retrieve any type of ledger object by its unique ID
  2. account_root - Retrieve an AccountRoot object. This is roughly equivalent to the account_info command.
  3. directory - Retrieve a DirectoryNode, which contains a list of other ledger objects
  4. offer - Retrieve an Offer object, which defines an offer to exchange currency
  5. ripple_state - Retrieve a RippleState object, which tracks a (non-XRP) currency balance between two accounts.

If you specify more than one of the above items, the server retrieves only of them; it is undefined which it chooses.

The full list of parameters recognized by this method is as follows:

Field Type Description
index String (Optional) Specify the unique identifier of a single ledger entry to retrieve.
account_root String - [Address][] (Optional) Specify an AccountRoot object to retrieve.
directory Object or String (Optional) Specify a DirectoryNode. (DirectoryNode objects each contain a list of IDs for things contained in them.) If a string, interpret as the unique index to the directory, in hex. If an object, requires either dir_root or owner as a sub-field, plus optionally a sub_index sub-field.
directory.sub_index Unsigned Integer (Optional) If provided, jumps to a later "page" of the Directory.
directory.dir_root String (Required if directory is specified as an object and directory.owner is not provided) Unique index identifying the directory to retrieve, as a hex string.
directory.owner String (Required if directory is specified as an object and directory.dir_root is not provided) Unique address of the account associated with this directory
offer Object or String (Optional) Specify an Offer object to retrieve. If a string, interpret as the unique index to the Offer. If an object, requires the sub-fields account and seq to uniquely identify the offer.
offer.account String - [Address][] (Required if offer specified) The account that placed the offer.
offer.seq Unsigned Integer (Required if offer specified) The sequence number of the transaction that created the Offer object.
ripple_state Object (Optional) Object specifying the RippleState (trust line) object to retrieve. The accounts and currency sub-fields are required to uniquely specify the RippleState entry to retrieve.
ripple_state.accounts Array (Required if ripple_state specified) 2-length array of account [Address][]es, defining the two accounts linked by this RippleState object
ripple_state.currency String (Required if ripple_state specified) [Currency Code][] of the RippleState object to retrieve.
binary Boolean (Optional) If true, return the requested ledger object's contents as a hex string. Otherwise, return data in JSON format. The default is true if searching by index and false otherwise.
ledger_hash String (Optional) A 20-byte hex string for the ledger version to use. (See Specifying a Ledger)
ledger_index String or Unsigned Integer (Optional) The sequence number of the ledger to use, or a shortcut string to choose a ledger automatically. (See Specifying a Ledger)

The response follows the standard format, with a successful result containing the following fields:

Field Type Description
index String Unique identifying key for this ledger_entry
ledger_index Unsigned Integer Unique sequence number of the ledger from which this data was retrieved
node Object (Omitted if "binary": true specified.) Object containing the data of this ledger object, according to the [ledger format][].
node_binary String (Omitted unless "binary":true specified) Binary data of the ledger object, as hex.

Possible Errors

  • Any of the universal error types.
  • invalidParams - One or more fields are specified incorrectly, or one or more required fields are missing.
  • lgrNotFound - The ledger specified by the ledger_hash or ledger_index does not exist, or it does exist but the server does not have it.
