Introduction

This is a list of the simplewallet RPC calls, their inputs and outputs, and examples of each.

All simplewallet methods use the same JSON RPC interface. For example:

IP=127.0.0.1
PORT=18082
METHOD="make_integrated_address"
PARAMS="{\"payment_id\":\"1234567890123456789012345678900012345678901234567890123456789000\"}"
curl \
    -X POST http://$IP:$PORT/json_rpc \
    -d '{"jsonrpc":"2.0","id":"0","method":"'$METHOD'","params":'"$PARAMS"'}' \
    -H 'Content-Type: application/json'

Note: "atomic units" refer to the smallest fraction of 1 XMR according to the bitmonerod implementation. 1 XMR = 1e12 atomic units.

JSON RPC Methods:

getbalance

Return the wallet's balance.

Inputs: None.

Outputs:

  • balance - unsigned int; The total balance of the current simplewallet in session.
  • unlocked_balance - unsigned int; Unlocked funds are those funds that are sufficiently deep enough in the Monero blockchain to be considered safe to spend.

Example:

{:.cli-code} [ monero->~ ]$ curl -X POST http://127.0.0.1:18082/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"getbalance"}' -H 'Content-Type: application/json' { "id": "0", "jsonrpc": "2.0", "result": { "balance": 140000000000, "unlocked_balance": 50000000000 } }

getaddress

get_bulk_payments

Get a list of incoming payments using a given payment id, or a list of payments ids, from a given height. This method is the preferred method over get_payments because it has the same functionality but is more extendable. Either is fine for looking up transactions by a single payment ID.
