Daemon 📞 RPC calls
Introduction
This is a list of the oxend 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 $OXEN according to the oxend implementation. 1 $OXEN = 1e12 atomic units.

JSON RPC Methods
The majority of oxend RPC calls use the daemon's json_rpc interface to request various bits of information. These methods all follow a similar structure, for example:
1
IP=127.0.0.1
2
PORT=18081
3
METHOD='get_block_header_by_height'
4
ALIAS='getblockheaderbyheight'
5
PARAMS='{"height":912345}'
6
curl \
7
    -X POST http://$IP:$PORT/json_rpc \
8
    -d '{"jsonrpc":"2.0","id":"0","method":"'$METHOD'","params":'$PARAMS'}' \
9
    -H 'Content-Type: application/json'

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

get_last_block_header
Block header information for the most recent block is easily retrieved with this method. No inputs are needed.
Alias: getlastblockheader.
Inputs: None.
Outputs:
block_header - A structure containing block header information.
block_size - unsigned int; The block size in bytes.
depth - unsigned int; The number of blocks succeeding this block on the blockchain. A larger number means an older block.

nonce - unsigned int; a cryptographic random one-time number used in mining a $OXEN block.
num_txes - unsigned int; Number of transactions in the block, not counting the coinbase tx.
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 generated in this block and rewarded to the miner. Note: 1 $OXEN = 1e12 atomic units.
timestamp - unsigned int; The unix time at which the block was recorded into the blockchain.
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 (false).

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.
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.
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 (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):
