neurai-rpc

A package that will help you do RPC calls from Node.js to your Neurai node, that is your full Neurai node.

URLs for locally installed Neurai nodes.

• http://127.0.0.1:19001 for mainnet (Standard RPC)
• http://127.0.0.1:19002 for mainnet (DePIN Messaging)
• http://127.0.0.1:19101 for testnet (Standard RPC)
• http://127.0.0.1:19102 for testnet (DePIN Messaging)

Neurai as a service, you don't need your own node

• https://rpc-main.neurai.org/rpc for mainnet
• https://rpc-testnet.neurai.org/rpc for testnet

Install

npm install @neuraiproject/neurai-rpc

Standard RPC Usage

Example using ES modules

This example uses Neurai as a service from https://rpc-main.neurai.org.

In node.js you need to give the file the ending .mjs for modular JavaScript. Like example.mjs

import { getRPC, methods } from "@neuraiproject/neurai-rpc";

const username = "anonymous";
const password = "anonymous";
const URL = "https://rpc-main.neurai.org/rpc";
const rpc = getRPC(username, password, URL);

const params = [];
rpc(methods.getblockcount, params).then(console.log);

Example using CommonJS

const { getRPC, methods } = require("@neuraiproject/neurai-rpc");
//methods is a list of all available methods/functions/commands/procedures

const rpc = getRPC("UsernameSecret", "PasswordSecret", "http://localhost:19001");

const promise = rpc(methods.getassetdata, ["ELVIS"]);
promise.catch((e) => {
  console.dir(e);
});

promise.then((response) => {
  console.log(response);
});

will print out

{ name: 'ELVIS', amount: 1, units: 8, reissuable: 1, has_ipfs: 0 }

DePIN Messaging Usage

DePIN (Decentralized Physical Infrastructure Network) messaging uses port 19002 and requires cryptographic signature authentication instead of username/password.

Basic DePIN Example

import { getDePinRPC } from "@neuraiproject/neurai-rpc";

// Function to sign messages with your private key
async function signMessage(message) {
  // Implement your signing logic here
  // Return base64-encoded signature
  return "signature_base64";
}

const depinRPC = await getDePinRPC({
  depinUrl: "http://localhost:19002",
  address: "NYourAddressHere",
  signMessage: signMessage
});

// Send a DePIN message
const result = await depinRPC("depinsendmsg", [
  "FRANCE",
  "192.168.1.100:19002",
  "Hello team!",
  "NYourAddressHere"
]);
console.log(result);

For complete DePIN examples including browser wallet integration, error handling, and advanced usage, see DEPIN_EXAMPLES.md.

The messaging token configured for a DePIN gateway can be any asset. Separately, the dedicated DePIN asset-management RPCs work with the newer &ASSET DePIN asset type, which is soulbound, documented here as enabled for mainnet and testnet, and must use units=0.

DePIN Authentication

Port 19002 uses a challenge-response authentication protocol:

1. Client requests a challenge from the server
2. Server returns a random challenge string with expiration time (60 seconds)
3. Client signs the challenge with their private key
4. Client sends RPC request with address and signature
5. Server verifies the signature against the address

The getDePinRPC function handles this authentication flow automatically, including challenge caching and automatic retry on expiration.

Example list all generated addresses in a Wallet (Raven core)

Use method listreceivedbyaddress to receive a list of all generated addresses. Write the result to a .json file

const { getRPC, methods } = require("@neuraiproject/neurai-rpc");
//methods is a list of all available methods/functions/commands/procedures

const method = methods.listreceivedbyaddress;
const minConfirmations = 1;
const includeEmpty = true;

const params = [minConfirmations, includeEmpty];

const rpc = getRPC("UsernameSecret", "PasswordSecret", "http://localhost:19001");

const promise = rpc(method, params);
promise.catch((e) => {
  console.dir(e);
});

promise.then((response) => {
  const addresses = [];
  response.map(function (obj) {
    addresses.push(obj.address);
  });
  writeToFile(addresses);
  console.log("DONE, check out addresses.json");
});

function writeToFile(list){
    const json = JSON.stringify(list, null, 4);
    require("fs").writeFileSync("./addresses.json", json);

}
