Ixian uses HTTP GET requests for communication with the API and always responds with a JSON response in the body of the HTTP response.

The response looks generally like this:

{
    "id": [currently unused],
    "result": [object],
    "error": {
        "code": [integer],
        "message": [string]
    }
}

All three fields are optional, but either "result" or "error" will always be present. The structure of the "result" field is dependent on the type of query - please see specific API commands for details.

Add Transaction

Generates a new IXI transaction to transfer funds between wallets. Multiple 'from' wallets with different amounts may be specified, as well as multiple target wallets and amounts.

Note: If you do not specify from, the required funds and fee will be deducted from the node's addresses (the order is unspecified). Multiple addresses may be used if the first one chosen does not have sufficient funds. Alternatively, if you do specify from, your total amount must include the required transaction fee. The transaction fee may be calculated in multiple ways:

  • Call the API createrawtransaction, which will generate a transaction object but not send it to the network. In this way you can measure the object's size and calculate an appropriate fee. This API takes the same parameters as addtransaction.
  • Call the API calculatetransactionfee, which will return the required fee amount for the given transaction. This API takes the same parameters as addtransaction.
  • Use the autofee parameter, which will deduct the required transaction fee from the first specified from address. The address must have sufficient funds to cover both the amount and fee. You can change the order of from addresses to ensure this.

Method: addtransaction

Input parameters:

Parameter Type Required Description
to String Yes List of Base58 encoded recipient addresses with their amounts. Amounts are separated by '_' character. Addresses are separated by '-' character (i.e. address1_amount1-address2_amount2)
from String No List of Base58 encoded sending addresses with their amounts. Amounts are separated by '_' character. Addresses are separated by '-' character (i.e. address1_amount1-address2_amount2). All addresses must belong to the same private key. If no from parameter is specified, it will be automatically generated, where the addresses with least IxiCash will be spent first.
fee Number No Transaction fee, specified in IxiCash per kB. If no fee parameter is specified, the default (which is also the minimum) 0.00005 IxiCash per kB will be used.
autofee Boolean No If specified, the system will automatically deduct the required fee from the first address given in from. This parameter is not required if you have included the appropriate fees somewhere in the from list, or are not specifying the from list at all.

Output:

  • success: transaction details are returned as a JSON object and the error field is set to null:
  • fail JSON encoded details with a non-null error and a null result:

Errors:

Error Description
RPC_INVALID_ADDRESS_OR_KEY Addresses specified in the "from" parameter does not belong to this node.
RPC_INVALID_PARAMS Invalid "from" amounts, or invalid "to" addresses or amounts were specified.
RPC_VERIFY_ERROR The transaction does not pass verification - this usually means that no usable "from" addresses were present, or there was something wrong with the signing key.
RPC_WALLET_INSUFFICIENT_FUNDS Address or addresses specified have insufficient balance to be used for the transaction.
RPC_TRANSACTION_ERROR An error occured while adding the transaction, check the message and log file for details.
RPC_INTERNAL_ERROR An unexpected error occured within the node. Please see the node log for details.

Create Raw Transaction

Generates a new IXI transaction, but doesn't add it to the Transaction Pool. This enables manual TX fee calculations and features such as offline transactions.

Note: If you do not specify from, the required funds and fee will be deducted from the node's addresses (the order is unspecified). Multiple addresses may be used if the first one chosen does not have sufficient funds. If you do specify from, it will not include any transaction fees. It is up to the caller of this API to examine the returned Transaction object and add the fee in the from list. This allows greater flexibility than autofee or not specifying the from list.
Note: The transaction is returned in a raw (binary) form, encoded as a hexadecimal string. In order to convert it into a JSON object, use the API call Decode Raw Transaction.
Note: The returned transaction is not signed.

Method: createrawtransaction

Input parameters:

Parameter Type Required Description
to String Yes List of Base58 encoded recipient addresses with their amounts. Amounts are separated by '_' character. Addresses are separated by '-' character (i.e. address1_amount1-address2_amount2)
from String No List of Base58 encoded sending addresses with their amounts. Amounts are separated by '_' character. Addresses are separated by '-' character (i.e. address1_amount1-address2_amount2). All addresses must belong to the same private key. If no from parameter is specified, it will be automatically generated, where the addresses with least IxiCash will be spent first.
fee Number No Transaction fee, specified in IxiCash per kB. If no fee parameter is specified, the default (which is also the minimum) 0.00005 IxiCash per kB will be used.
autofee Boolean No If specified, the system will automatically deduct the required fee from the first address given in from. This parameter is not required if you have included the appropriate fees somewhere in the from list, or are not specifying the from list at all.

Output:

  • success: transaction is returned as a hexadecimal string and the error field is set to null. This transaction is not added to the network.
  • fail JSON encoded details with a non-null error and a null result:

Errors:

Error Description
RPC_INVALID_ADDRESS_OR_KEY Addresses specified in the "from" parameter does not belong to this node.
RPC_INVALID_PARAMS Invalid "from" amounts, or invalid "to" addresses or amounts were specified.

Delete MultiSig Key

Deletes the specified address from the 'allowed signers' list of the target multisig wallet. If all other signers, except the original wallet owner, are removed, the wallet will be converted into a normal wallet.
Note: You cannot use this to remove the original owner of the wallet. You cannot remove a signer if doing so will leave the wallet unusuable (if the change would bring the number of allowed signers below the required signatures).

Method: delmultisigkey

Input parameters:

Parameter Type Required Description
wallet String Yes The wallet where the specified signer will be removed from allowed signers.
signer String Yes The signing address which will be removed from the target wallet.

Errors:

Error Description
RPC_INVALID_PARAMS One or more of the required parameters are missing or invalid.
RPC_INTERNAL_ERROR An unknown error occured while creating the transaction - please check the node's log file.

Output:

  • success: the transaction is added to the Transaction Pool and broadcast to the network and the Transaction object is returned.
  • fail: JSON encoded details with a non-null error and a null result

Example:

{
    "result": {

Change MultiSig Required Signatures

Changes the required number of signatures on a multisig wallet. The required number of signatures is the minimum number of additional signatures for any transaction performed on a multisig wallet before the transaction is executed.
Note: The required number of signatures cannot be increased to such a value that would make the wallet unusuable. (More required signatures than allowed signers.
Note: Any combination of allowed signatures will enable the transaction, as long as the number of required signatures is reached.

Method: changemultisigs

Input parameters:

Parameter Type Required Description
wallet String Yes The multisig wallet which will have its required signatures alterred.
sigs String Yes New number of signatures.

Errors:

Error Description
RPC_INVALID_PARAMS One or more of the required parameters are missing or invalid.
RPC_INVALID_PARAMETER The sigs parameter was not a number or was out of range.
RPC_INTERNAL_ERROR An unknown error occured while creating the transaction - please check the node's log file.

Output:

  • success: the transaction is added to the Transaction Pool and broadcast to the network and the Transaction object is returned.
  • fail: JSON encoded details with a non-null error and a null result
