Node API Reference

Usage

The JSON-RPC API can be consumed through different transports: TCP, HTTP and Websockets. The node operator can enable or disable the JSON-RPC service, as well as specify a different network address for each transport in the node's configuration file. By default, the tcp port is set to be 21338, http to 21339 and the ws to 21340.

Sensitive methods

Sensitive methods are those that either use the node's master key or provide information that may compromise the node's public key or address, or even the node's private key itself.

Sensitive methods allow node operators to easily manage their own nodes from a command line interface within the same host or private network. By default, sensitive methods are enabled.

When exposing any of the JSON-RPC ports (tcp/21388, http/21339, ws/21340) to a public IP, ensure to disable sensitive methods first by setting enable_sensitive_methods = false in your node's witnet.toml configuration file.

Public methods

Public methods provide information that do not compromise node's private information, like its private or public key, or address:

addPeers

Add one or more peer addresses to the list of available ones.

Parameters

Vec<SocketAddr>

Returns

true

Example

{
    "jsonrpc":"2.0",

syncStatus

Get node synchronization status.

Parameters

None

Returns

SyncStatus: Map with the chain beacon, the current epoch and the state of the node. Values of node state are:

WaitingConsensus: waiting for reaching consensus between its peers
Synchronizing: synchronization process.
AlmostSynced: it has all the blocks in the chain and is ready to start consolidating block candidates in real time.
Synced: can consolidate block candidates, propose its own candidates (mining) and participate in resolving data requests (witnessing).

Example

{"jsonrpc":"2.0","id":1,"method":"syncStatus","params": []}

{
   "jsonrpc":"2.0",
   "result":{
      "chain_beacon":{
         "checkpoint":2016476,
         "hashPrevBlock":"59ea553498c85bad0426f08420df943abed61c2559fb11321b7d9293488efbb2"
      },
      "current_epoch":2016477,
      "node_state":"Synced"
   },
   "id":1
}

tryRequest

Ask your node to resolve data request locally, without actually broadcasting it to the Witnet network.

Parameters

DataRequestOutput: unsigned data request struct with retrievals' script and filters' argsfields encoded as CBOR values serialized as Vec<u8> arrays.

Returns

Data request result stringified as a RadonTypes value.

Example

ETH/USD data request
