Introduction

This is a list of the monero-wallet-rpc calls, their inputs and outputs, and examples of each. The program monero-wallet-rpc replaced the rpc interface that was in simplewallet and then monero-wallet-cli.

All monero-wallet-rpc 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'

If the monero-wallet-rpc was executed with the --rpc-login argument as username:password, then follow this example:

IP=127.0.0.1
PORT=18082
METHOD="make_integrated_address"
PARAMS="{\"payment_id\":\"1234567890123456789012345678900012345678901234567890123456789000\"}"
curl \
    -u username:password --digest \
    -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 monerod implementation. 1 XMR = 1e12 atomic units.

Index of JSON RPC Methods:


JSON RPC Methods:

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.
