NoLimitNodes is a powerful service that offers REST APIs and Websockets for interacting with the Solana blockchain. Whether you’re a beginner exploring Solana or a seasoned developer, NoLimitNodes provides an easy-to-use interface to access real-time blockchain data. This guide will walk you through setting up and using NoLimitNodes for your Solana-based projects.

1. Getting Started with NoLimitNodes

Before you can start using NoLimitNodes, you need to set up an account and generate an API key. Here’s a quick overview of the process:

Go to the NoLimitNodes dashboard.

Generate an API key if you haven’t done so already.

You will receive two links:

  • REST API: https://api.nolimitnodes.com/solana?api_key=xxx
  • WebSocket: wss://api.nolimitnodes.com/solana?api_key=xxx

Keep your API key secure and do not expose it in public code or repositories.

2. Using the REST API

Request Example:

curl -X POST 'https://api.nolimitnodes.com/solana?api_key=xxx' \
 -H 'Content-Type: application/json' \
 -d '{
   "id": 1,
   "jsonrpc": "2.0",
   "method": "getEpochInfo"
}'

Response Example:

{
    "jsonrpc": "2.0",
    "result": {
        "absoluteSlot": 307196285,
        "blockHeight": 285572434,
        "epoch": 711,
        "slotIndex": 44285,
        "slotsInEpoch": 432000,
        "transactionCount": 347697747950
    },
    "id": 1
}

The above request fetches epoch information from the Solana network, providing details like the current epoch, block height, and the number of slots within that epoch. For more examples and detailed documentation, check the official NoLimitNodes documentation.

3. Using the WebSocket API

NoLimitNodes also provides a WebSocket API, which is useful for real-time updates and streaming data. You can use this to receive events directly from the Solana blockchain. Here’s how you can use it:

Socket Connect

To connect to the WebSocket and listen for events, you’ll need to use a WebSocket client library like websockets for Python. Here’s a simple example.

import asyncio
import websockets
import json

async def connect_to_socket():
    async with websockets.connect('wss://api.nolimitnodes.com/solana?api_key=xxx') as websocket:
        # Subscribe to logs subscription event
        await websocket.send(json.dumps({
            "jsonrpc": "2.0",
            "id": 1,
            "method": "logsSubscribe",
            "params": [
                {
                    "mentions": [
                        "6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P" # target account address (pump.fun)
                    ]
                },
                {
                    "commitment": "finalized"
                }
            ]
        }))

        while True:
            message = await websocket.recv()
            print(f"Received message: {message}")

asyncio.run(connect_to_socket())

Socket Response:

In this script, we are subscribing to the logs subscription event which sends a message whenever a new logs is finalized on the Solana network. The loop listens for and prints out incoming messages.

4. Best Practices

  • Secure your API key: Do not expose your API key in public code repositories or applications.
  • Use the appropriate methods: Make sure to use the NoLimitNodes REST and WebSocket APIs according to the official documentation to avoid rate limits and ensure stable performance.
  • Test with a small subset of data: Initially, test API requests and WebSocket connections with a small subset of data to verify functionality without risking performance issues.

For further details and examples, visit the official NoLimitNodes documentation.

NoLimitNodes offers a straightforward way to interact with the Solana network, whether for querying data via REST APIs or receiving real-time updates with WebSockets. By following this guide, you can effectively integrate NoLimitNodes into your Solana-based applications, making blockchain data more accessible and manageable for your development needs.
