Documentation

Daemon API

Initialisation

Instantiate a new Daemon object:

const Daemon = require('monero-rpc').Daemon
 
const daemon = new Daemon('http://localhost:18081')
const daemon = new Daemon('http://node.monero.hashvault.pro:18081') // or use a remote node

Methods

getLastBlockHeight(callback)

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

daemon.getLastBlockHeight((err, height) => {
    if (err) return console.log(err)
    console.log(height) // 993163
})

getLastBlockHeader(callback)

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

daemon.getLastBlockHeader((err, header) => {
    if (err) return console.log(err)
    console.log(header)
    /*
     * {
     *     "depth": 0,
     *     "difficulty": 746963928,
     *     "hash": "ac0f1e2262...",
     *     "height": 990793,
     *     "major_version": 1,
     *     "minor_version": 1,
     *     "nonce": 1550,
     *     "orphan_status": false,
     *     "prev_hash": "386575e3b0...",
     *     "reward": 6856609225169,
     *     "timestamp": 1457589942
     * }
     */
})

getBlockHeader(id, callback)

Block header information can be retrieved using either a block's hash or height.

By height:

daemon.getBlockHeader(990793, (err, header) => {
    if (err) return console.log(err)
    console.log(header)
    /*
     * {
     *     "depth": 0,
     *     "difficulty": 746963928,
     *     "hash": "ac0f1e2262...",
     *     "height": 990793,
     *     "major_version": 1,
     *     "minor_version": 1,
     *     "nonce": 1550,
     *     "orphan_status": false,
     *     "prev_hash": "386575e3b0...",
     *     "reward": 6856609225169,
     *     "timestamp": 1457589942
     * }
     */
})

By hash:

daemon.getBlockHeader('ac0f1e2262...', (err, header) => {
    if (err) return console.log(err)
    console.log(header)
    /*
     * {
     *     "depth": 0,
     *     "difficulty": 746963928,
     *     "hash": "ac0f1e2262...",
     *     "height": 990793,
     *     "major_version": 1,
     *     "minor_version": 1,
     *     "nonce": 1550,
     *     "orphan_status": false,
     *     "prev_hash": "386575e3b0...",
     *     "reward": 6856609225169,
     *     "timestamp": 1457589942
     * }
     */
})

getBlock(id, callback)

Full block information can be retrieved by either block height or hash, like with the block header calls.

daemon.getBlock('ac0f1e2262...', (err, block) => {
    if (err) return console.log(err)
    console.log(block) // { ... }
})

getBlockTemplate(address, reserved, callback)

daemon.getBlockTemplate('46tFLJPaNyy...', 17, (err, template) => {
    if (err) return console.log(err)
    console.log(template) // { ... }
})

submitBlock(blob, callback)

Submit a block to the network.

daemon.submitBlock('...', (err) => {
    if (err) return console.log(err)
    console.log('hurray') // 'hurray'
})

getKeyImagesSpent(keyImages, callback)

Check if a key image is spent.

daemon.getKeyImagesSpent(['8d1bd818...', '7319134bf...'], (err, status) => {
    if (err) return console.log(err)
    console.log(status) // [1, 1]
})

stop(callback)

daemon.stop((err) => {
    if (err) return console.log(err)
    console.log(':(') // ':('
})

getInfo(callback)

Get miscellaneous information about the state of this daemon and the network.

daemon.getInfo((err, info) => {
    if (err) return console.log(err)
    console.log(info)
    /*
     * {
     *     "alt_blocks_count": 5,
     *     "difficulty": 972165250,
     *     "grey_peerlist_size": 2280,
     *     "height": 993145,
     *     "incoming_connections_count": 0,
     *     "outgoing_connections_count": 8,

     *     "testnet": false,
     *     "top_block_hash": "",
     *     "tx_count": 564287,

daemon.isTestnet((err, testnet) => {
    if (err) return console.log(err)
    console.log(testnet) // false
})
