Daemon RPC

Introduction

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

Many RPC calls use the daemon's JSON RPC interface while others use their own interfaces, as demonstrated below.

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

JSON RPC Methods:

• get_block_count
• on_get_block_hash
• get_block_template
• submit_block
• get_last_block_header

JSON RPC Methods

The majority of monerod RPC calls use the daemon's json_rpc interface to request various bits of information. These methods all follow a similar structure, for example:

IP=127.0.0.1
PORT=18081
METHOD='get_block_header_by_height'
ALIAS='getblockheaderbyheight'
PARAMS='{"height":912345}'
curl \
    http://$IP:$PORT/json_rpc \
    -d '{"jsonrpc":"2.0","id":"0","method":"'$METHOD'","params":'$PARAMS'}' \
    -H 'Content-Type: application/json'

Some methods include parameters, while others do not. Examples of each JSON RPC method follow.

get_block_count

Look up how many blocks are in the longest chain known to the node.

Alias: getblockcount.

Inputs: None.

Outputs:

• count - unsigned int; Number of blocks in longest chain seen by the node.
• status - string; General RPC error code. "OK" means everything looks good.
• untrusted - boolean; States if the result is obtained using the bootstrap mode, and is therefore not trusted (true), or when the daemon is fully synced and thus handles the RPC locally (false)

Example:

$ curl http://127.0.0.1:18081/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"get_block_count"}' -H 'Content-Type: application/json'

get_block

Full block information can be retrieved by either block height or hash, like with the above block header calls. For full block information, both lookups use the same method, but with different input parameters.

Alias: getblock.

Inputs (pick one of the following):

• height - unsigned int; The block's height.
• hash - string; The block's hash.

Outputs:

• blob - string; Hexadecimal blob of block information.
• block_header - A structure containing block header information. See get_last_block_header.
• credits - unsigned int; If payment for RPC is enabled, the number of credits available to the requesting client. Otherwise, 0.
• json - json string; JSON formatted block details:
  • major_version - Same as in block header.
  • minor_version - Same as in block header.
  • timestamp - Same as in block header.
  • prev_id - Same as prev_hash in block header.
  • nonce - Same as in block header.
  • miner_tx - Miner transaction information
    • version - Transaction version number.
    • unlock_time - The block height when the coinbase transaction becomes spendable.
    • vin - List of transaction inputs:
      • gen - Miner txs are coinbase txs, or "gen".
        • height - This block height, a.k.a. when the coinbase is generated.
    • vout - List of transaction outputs. Each output contains:
      • amount - The amount of the output, in @atomic-units.
      • target -
        • key -
    • extra - Usually called the "transaction ID" but can be used to include any random 32 byte/64 character hex string.
    • signatures - Contain signatures of tx signers. Coinbased txs do not have signatures.
  • tx_hashes - List of hashes of non-coinbase transactions in the block. If there are no other transactions, this will be an empty list.
• status - string; General RPC error code. "OK" means everything looks good.
• top_hash - string; If payment for RPC is enabled, the hash of the highest block in the chain. Otherwise, empty.
• untrusted - boolean; States if the result is obtained using the bootstrap mode, and is therefore not trusted (true), or when the daemon is fully synced and thus handles the RPC locally (false)

Look up by height:

In the following example, block 912345 is looked up by its height. Note that block 912345 does not have any non-coinbase transactions. (See the next example for a block with extra transactions):

Other Daemon RPC Calls

Not all daemon RPC calls use the JSON_RPC interface. This section gives examples of these calls.

The data structure for these calls is different than the JSON RPC calls. Whereas the JSON RPC methods were called using the /json_rpc extension and specifying a method, these methods are called at their own extensions. For example:

IP=127.0.0.1
PORT=18081
METHOD='gettransactions'
PARAMS='{"txs_hashes":["d6e48158472848e6687173a91ae6eebfa3e1d778e65252ee99d7515d63090408"]}'
curl \
	http://$IP:$PORT/$METHOD \
	-d $PARAMS \
	-H 'Content-Type: application/json'

Note: It is recommended to use JSON RPC where such alternatives exist, rather than the following methods. For example, the recommended way to get a node's height is via the JSON RPC methods get_info or get_last_block_header, rather than getheight below.

For calls that end with .bin, the data is exchanged in the form of binary, serialized objects, as defined in the Core RPC Server.

/get_height

Get the node's current height.

Alias: /getheight.

Inputs: None.

Outputs:

• hash - string; The block's hash.
• height - unsigned int; Current length of longest chain known to daemon.
• status - string; General RPC error code. "OK" means everything looks good.
• untrusted - boolean; States if the result is obtained using the bootstrap mode, and is therefore not trusted (true), or when the daemon is fully synced and thus handles the RPC locally (false)

$ curl http://127.0.0.1:18081/get_height -H 'Content-Type: application/json'

{
