Quick Start Guide

This guide will help you quickly integrate TheRPC into your project. Follow these steps to start making blockchain API calls.

Step 1: Get an API Key

To use TheRPC, you'll need an API key:

  1. Sign up at TheRPC.io
  2. Navigate to the dashboard
  3. Create or retrieve your API key

Step 2: Choose Your Network

TheRPC supports multiple networks. Configure your environment with your API endpoint and key:

API_ENDPOINT="YOUR_API_ENDPOINT"
API_KEY="YOUR_API_KEY"

Step 3: Make Your First Call

Here are basic examples for different programming languages. For more comprehensive examples and language-specific features, check out our Tools & SDKs Overview.

Using Curl

curl --request POST ${API_ENDPOINT} \
  --header 'Content-Type: application/json' \
  --header 'Authorization: Bearer ${API_KEY}' \
  --data '{
    "jsonrpc": "2.0",
    "method": "eth_blockNumber",
    "params": [],
    "id": 1
  }'

Using JavaScript

const axios = require('axios');

const config = {
	url: 'YOUR_API_ENDPOINT',
	apiKey: 'YOUR_API_KEY',
};

async function getBlockNumber() {
	const response = await axios.post(
		config.url,
		{
			jsonrpc: '2.0',
			method: 'eth_blockNumber',
			params: [],
			id: 1,
		},
		{
			headers: {
				'Content-Type': 'application/json',
				Authorization: `Bearer ${config.apiKey}`,
			},
		},
	);

	console.log('Latest Block Number:', response.data.result);
}

Using Python

import requests

config = {
    'url': 'YOUR_API_ENDPOINT',
    'api_key': 'YOUR_API_KEY'
}

def get_block_number():
    response = requests.post(
        config['url'],
        headers={
            'Content-Type': 'application/json',
            'Authorization': f"Bearer {config['api_key']}"
        },
        json={
            'jsonrpc': '2.0',
            'method': 'eth_blockNumber',
            'params': [],
            'id': 1
        }
    )
    return response.json()['result']

Step 4: Using Web3 Libraries

For more complex interactions, we recommend using Web3 libraries. You can find detailed examples for all supported languages and frameworks in our Tools & SDKs documentation.

Web3.js (JavaScript)

const Web3 = require('web3');
const web3 = new Web3('YOUR_API_ENDPOINT');

// Add API key to requests
web3.setHeader('Authorization', 'Bearer YOUR_API_KEY');

async function getBalance(address) {
	const balance = await web3.eth.getBalance(address);
	return web3.utils.fromWei(balance, 'ether');
}

Web3.py (Python)

from web3 import Web3
from web3.middleware import http_retry_request_middleware

w3 = Web3(Web3.HTTPProvider(
    'YOUR_API_ENDPOINT',
    request_kwargs={
        'headers': {'Authorization': 'Bearer YOUR_API_KEY'}
    }
))

# Add retry middleware
w3.middleware_onion.add(http_retry_request_middleware)

Available Methods

All supported API methods with examples in different programming languages can be found in our Ethereum Methods documentation. This includes:

  • Detailed method descriptions
  • Request and response formats
  • Language-specific code examples
  • Common use cases

Network Selection

When using TheRPC, you'll receive specific API endpoints for each network you want to access. Simply replace YOUR_API_ENDPOINT with the appropriate endpoint for your chosen network.
