## 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.**

## JSON RPC Methods:
### getbalance
Return the wallet's balance.
Inputs: *None*.
Outputs:
* *balance* - unsigned int; The total balance of the current monero-wallet-rpc 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}

}
}
### 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.

* *unlock_time* - unsigned int
Example:
{:.cli-code}
<span style="color: cyan;">[ monero->~ ]$</span> curl -X POST http://127.0.0.1:18082/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"get_bulk_payments","params":{"payment_ids":["4279257e0a20608e25dba8744949c9e1caff4fcdafc7d5362ecf14225f3d9030"],"min_block_height":990000}}' -H 'Content-Type: application/json'
