Dash (DASH)

Dash API Reference for blockchain access through Dash nodes, including JSON-RPC, REST, and Blockbook APIs.

Dash is a Layer 1 proof-of-work blockchain, derived from Bitcoin, built for fast and low-cost payments. Its distinguishing feature is a two-tier network: miners secure the chain with the X11 proof-of-work algorithm, while a layer of collateralized masternodes provides InstantSend (near-instant, locked payments), ChainLocks (protection against deep reorganizations), and on-chain governance. It keeps Bitcoin's UTXO model and a Bitcoin Core-style JSON-RPC interface, and is served by the Dash Core node software. GetBlock exposes Dash over four interfaces: Core JSON-RPC, Bitcoin-style REST, and the Blockbook indexer's REST and WebSocket APIs.

Key Features

• Two-Tier Network: Miners plus collateralized masternodes that provide advanced services

• InstantSend: Masternode quorums lock transactions for near-instant, spend-safe confirmation

• ChainLocks: Quorum-signed blocks that protect against deep chain reorganizations

• UTXO Model: Uses the unspent transaction output model inherited from Bitcoin

• X11 Proof of Work: Secured by the chained X11 hashing algorithm

• Bitcoin Core RPC: Exposes a JSON-RPC interface familiar to Bitcoin developers, plus Dash extensions

• Indexer APIs: Blockbook adds address-indexed REST and WebSocket access on top of the node

TECHNICAL DISCLAIMER: AUTHORITATIVE JSON-RPC API SPECIFICATION.

GetBlock's RPC API reference documentation is provided exclusively for informational purposes and to optimize the developer experience. The canonical and normative specification for Dash Core RPC methods is maintained and published through the official Dash Core documentation, and the Blockbook REST/WebSocket API is specified by the Blockbook project. These resources constitute the authoritative references.

Quickstart

Javascript(Axios)

1

Setup project

mkdir dash-api-quickstart && cd dash-api-quickstart && npm init --yes

2

Install Axios

npm install axios

3

Add code

index.js

const axios = require('axios');

const url = 'https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/';

const payload = {
  jsonrpc: '2.0',
  method: 'getblockcount',
  params: [],
  id: 'getblock.io'
};

axios.post(url, payload, {
  headers: { 'Content-Type': 'application/json' }
})
.then(response => {
  console.log('Current block height:', response.data.result);
})
.catch(error => console.error(error));

4

Run the script

node index.js

5

Response

Current block height: 2535413

Python(Request)

1

Setup project

mkdir dash-api-quickstart && cd dash-api-quickstart
python -m venv venv && source venv/bin/activate

2

Install requests

pip install requests

3

Add code

main.py

import requests
import json

url = "https://shared.eu-central-1.getblock.io/<ACCESS-TOKEN>/"

payload = json.dumps({
    "jsonrpc": "2.0",
    "method": "getblockcount",
    "params": [],
    "id": "getblock.io"
})

headers = {
    'Content-Type': 'application/json'
}

response = requests.post(url, headers=headers, data=payload)
print(response.text)

4

Run the script

python main.py

APIs

• JSON-RPC API — Dash Core JSON-RPC (Bitcoin-style + masternode/quorum methods)

• REST API — Bitcoin Core-style REST endpoints (/rest/...)

• Blockbook REST API — address-indexed indexer REST (/api/...)

• Blockbook WebSocket API — indexer WebSocket (queries + subscriptions)
