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:

IP=127.0.0.1
PORT=18081
METHOD='get_block_header_by_height'
ALIAS='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.

Alias: getblockcount.

Inputs: None.

Outputs:

• count - unsigned int; Number of blocks in longest chain seen by the node.

    "message": "Block not accepted"
  }
}

get_last_block_header

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.

  • 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.

  • difficulty - unsigned int; The strength of the Oxen network

  • 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 Oxen protocol at this block height.

  • 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).

In this example, the most recent block (1562023 at the time) is returned:

• hash - string; The block's sha256 hash.

Outputs:

• block_header - A structure containing block header information. See get_last_block_header.

  }
}

get_block_header_by_height

Similar to get_block_header_by_hash above, this method includes a block's height as an input parameter to retrieve basic information about the block.

Alias: getblockheaderbyheight.

Inputs:

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

Outputs:

• block_header - A structure containing block header information. See get_last_block_header.

• 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).

In this example, block 912345 is looked up by its height (notice that the returned information is the same as in the previous example):

$ curl -X POST http://127.0.0.1:18081/json_rpc -d '{"jsonrpc":"2.0","id":"0","method":"get_block_header_by_height","params":{"height":912345}}' -H 'Content-Type: application/json'

    },
    "status": "OK",
    "untrusted": false
  }
}

get_block_headers_range

Similar to get_block_header_by_height above, but for a range of blocks. This method includes a starting block height and an ending block height as parameters to retrieve basic information about the range of blocks.

Alias: getblockheadersrange.

Inputs:

• start_height - unsigned int; The starting block's height.

• end_height - unsigned int; The ending block's height.

Outputs:

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):

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 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.
