ZumCoind RPC API Interface

We expose all of the ZumCoind RPC API commands via the ZumCoind interface. Each of the below methods are Javascript Promises. For safety sake, always handle your promise catches as we do use them properly.

Methods noted having options have parameters that may be optional or required as documented.

daemon.getBlocks(options)

Returns information on the last 30 blocks before height (inclusive).

Method Parameters

Argument	Mandatory	Description	Format
height	Yes	The height of the blockchain to start at	integer

Example Code

daemon.getBlocks({
  height: 10000
}).then((blocks) => {
  // do something
})

daemon.getBlocks(options)

Not implemented

daemon.queryBlocks(options)

Not implemented

daemon.queryBlocksLite(options)

Retrieves the last 100 blocks from the last block hash that the daemon knows about in the list provided

For the best results, the block hashes you supply should follow the following order:

The first 10 blocks are sequential descending, next goes in pow(2,n), like 2, 4, 8, 16, 32, 64 and so on, and the last one is always genesis block

Method Parameters

Argument	Mandatory	Description	Format
blockHashes	Yes	The block hashes to query	strings
timestamp	No	The timestamp to query	integer

Example Code

daemon.queryBlocksLite({
  blockHashes: [
    '5b926d9fac41fbc53bf7c5ffc7e45e345f8c26aaefec9d3f9b019097a8827c12',

daemon.getWalletSyncData(options)

Returns up to 100 blocks. If block hash checkpoints are given, it will return beginning from the height of the first hash it finds, plus one.

However, if startHeight or startTimestamp is given, and this value is higher than the block hash checkpoints, it will start returning from that height instead.

The block hash checkpoints should be given with the highest block height hashes first.

Typical usage: specify a start height/timestamp initially, and from then on, also provide the returned block hashes.

Method Parameters

Argument	Mandatory	Description	Format
startHeight	No	The height to begin returning blocks from	integer
startTimestamp	No	The timestamp to begin returning blocks from (unix style)	integer
blockHashCheckpoints	No	The timestamp to begin returning blocks from	strings

Example Code

daemon.getWalletSyncData({
  startHeight: 1000,
  blockHashCheckpoints: [
    "0606a15147159e3f01dd90aa78828cf8587caed36203cd764701b56eb6ff6fd8",

daemon.getGlobalIndexesForRange(options)

Returns the global indexes for any transactions in the range [startHeight .. endHeight]. Generally, you only want the global index for a specific transaction, however, this reveals that you probably are the recipient of this transaction. By supplying a range of blocks, you can obfusticate which transaction you are enquiring about.

Note: key = transaction hash, value = global indexes for the outputs in that hash.

Method Parameters

Argument	Mandatory	Description	Format
startHeight	No	The height to begin returning indices from	integer
endHeight	No	The height to end returning indices from	integer

Example Code

daemon.getGlobalIndexesForRange({

ZumService RPC API Interface

We expose all of the zum-service RPC API commands via the ZumService interface. Each of the below methods are Javascript Promises. For safety sake, always handle your promise catches as we do use them properly.

Special Note: Any and all amounts/fees will already be in HUMAN readable units. DO NOT DIVIDE THEM AGAIN unless you've specified decimalDivisor as 1 in the options. You have been warned.

Unless otherwise noted, all methods will resolve the promise upon success and sample return data is supplied below. Any errors will reject the promise with an error condition.

Methods noted having options have parameters that may be optional or required as documented.
