GetBlock Solana RPC API documentation: JSON-RPC reference, WebSocket subscriptions, and connection guides for mainnet, devnet & alpenglow endpoints

Solana is a high-throughput Layer 1 blockchain launched in 2020 by Solana Labs, built around a single global state machine rather than sharding or rollups. It pairs Proof of History, a verifiable delay function that orders transactions before consensus, with Proof of Stake for validator selection, and executes non-conflicting transactions concurrently through the Sealevel runtime. The design targets sub-second confirmation for payments, order-book trading, and consumer applications that cannot tolerate multi-second block times.

Key Features

• Proof of History: A cryptographic clock orders transactions before consensus is reached

• 400ms Slot Time: Slots are scheduled roughly every 400 milliseconds, four per leader

• Parallel Execution: The Sealevel runtime executes transactions concurrently when account access sets do not overlap

• Local Fee Markets: Prioritization fees are priced per account, so congestion on one program does not raise fees network-wide

• SPL Token Standard: Fungible and non-fungible tokens are handled by the on-chain Token and Token-2022 programs

• Token Extensions: Token-2022 adds transfer fees, confidential transfers, and metadata without custom programs

• Versioned Transactions: Address lookup tables allow transactions to reference more accounts than the legacy format permits

• Stake-Weighted QoS: Transaction forwarding capacity is allocated in proportion to validator stake

Quickstart

In this section, you will learn how to make your first call with either:

• Axios

• Python

Before you begin, you must have already installed npm or yarn on your local machine (for the Axios example) or Python and pip (for the Python example).

Javascript(Axios)

1

Setup project

Create and initialize a new project:

mkdir solana-api-quickstart
cd solana-api-quickstart
npm init --yes

2

Install Axios

npm install axios

3

Create file

Create a new file named index.js. This is where you will make your first call.

4

Set ES module type

Set the ES module "type": "module" in your package.json.

5

Add code

Add the following code to index.js:

index.js

import axios from 'axios';

const data = JSON.stringify({
    "jsonrpc": "2.0",
    "method": "getSlot",
    "params": [],
    "id": "getblock.io"
});

const config = {
    method: 'post',
    url: 'https://go.getblock.io/<ACCESS-TOKEN>/',
    headers: {
        'Content-Type': 'application/json'
    },
    data: data
};

axios(config)
    .then(response => console.log(JSON.stringify(response.data)))
    .catch(error => console.log(error));

Replace <ACCESS-TOKEN> with your actual access token from GetBlock.

6

Run the script

node index.js

Expected output (example):

{
    "jsonrpc": "2.0",
    "result": 434717885,
    "id": "getblock.io"
}

Python(Request)

1

Set up the project folder

mkdir solana-api-quickstart
cd solana-api-quickstart

2

Create and activate a virtual environment

python -m venv venv
source venv/bin/activate

# On Windows, use venv\Scripts\activate

3

Install requests

pip install requests

4

Create the script

Create a file called main.py with the following code (replace <ACCESS-TOKEN> with your GetBlock access token):

import requests
import json

url = "https://go.getblock.io/<ACCESS-TOKEN>/"

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

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

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

5

Run the script

python main.py
