## Introduction
This is a list of the bitmonerod 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 bitmonerod implementation. **1 XMR = 1e12 atomic units.**

## JSON RPC Methods
The majority of bitmonerod 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='getblockheaderbyheight'
PARAMS='{"height":912345}'
curl \
-X POST 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.
### getblockcount
Look up how many blocks are in the longest chain known to the node.
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.
Example:

"status": "OK"
}
}
### on_getblockhash
Look up a block's hash by its height.
Inputs:

### submitblock
Submit a mined block to the network.
Inputs:
* Block blob data - string
Outputs:
* *status* - string; Block submit status.
### getlastblockheader
Block header information for the most recent block is easily retrieved with this method. No inputs are needed.
Inputs: *None*.
Outputs:
* *block_header* - A structure containing block header information.
* *depth* - unsigned int; The number of blocks succeeding this block on the blockchain. A larger number means an older block.
* *difficulty* - unsigned int; The strength of the Monero network based on mining power.
* *hash* - string; The hash of this block.
* *height* - unsigned int; The number of blocks preceding this block on the blockchain.
* *major_version* - unsigned int; The major version of the monero protocol at this block height.
* *minor_version* - unsigned int; The minor version of the monero protocol at this block height.
* *nonce* - unsigned int; a cryptographic random one-time number used in mining a Monero block.
* *orphan_status* - boolean; Usually `false`. If `true`, this block is not part of the longest chain.
* *prev_hash* - string; The hash of the block immediately preceding this block in the chain.
* *reward* - unsigned int; The amount of new atomic units generated in this block and rewarded to the miner. Note: 1 XMR = 1e12 atomic units.
* *timestamp* - unsigned int; The time the block was recorded into the blockchain.
* *status* - string; General RPC error code. "OK" means everything looks good.
In this example, the most recent block (990793 at the time) is returned:

### getblockheaderbyhash
Block header information can be retrieved using either a block's hash or height. This method includes a block's hash as an input parameter to retrieve basic information about the block.
Inputs:
* *hash* - string; The block's sha256 hash.
Outputs:
* *block_header* - A structure containing block header information. See [getlastblockheader](#getlastblockheader).
In this example, block 912345 is looked up by its hash:

"reward": 7388968946286,
"timestamp": 1452793716
},
"status": "OK"
}
}
### getblockheaderbyheight
Similar to `getblockheaderbyhash` above, this method includes a block's height as an input parameter to retrieve basic information about the block.
Inputs:
* *height* - unsigned int; The block's height.
Outputs:
* *block_header* - A structure containing block header information. See [getlastblockheader](#getlastblockheader).
In this example, block 912345 is looked up by its height (notice that the returned information is the save as in the previous example):
{:.cli-code}
<span style="color: cyan;">[ monero->~ ]$</span> curl -X POST http://127.0.0.1:18081/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"getblockheaderbyheight","params":{"height":912345}}' -H 'Content-Type: application/json'

"reward": 7388968946286,
"timestamp": 1452793716
},
"status": "OK"
}
}
### getblock
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.
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 [getlastblockheader](#getlastblockheader).
* *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.
**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 \
-X POST 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](#getinfo) or [getlastblockheader](#getlastblockheader), rather than [getheight](#getheight) below.
### /getheight
Get the node's current height.
Inputs: *None*.
Outputs:
* *height* - unsigned int; Current length of longest chain known to daemon.
