Create Your First Endpoint

An endpoint is your gateway to a blockchain network. Each endpoint includes:

An HTTPS RPC URL for standard calls
A WSS URL for WebSocket subscriptions
A unique API Key

Steps

1. Navigate to Endpoints

From the Dashboard, click Endpoints in the left sidebar (or visit /dashboard/endpoint).

2. Click "Add Endpoint"

Click the + Add Endpoint button in the top right corner.

3. Select a Blockchain

Choose from the available networks:

Network	Chain ID	Slug	Features
Ethereum	1	`ethereum-rpc`	Full; archive verification varies
Base	8453	`base-rpc`	Full; archive verification varies
BSC	56	`bsc-rpc`	Full; archive verification varies
Arbitrum One	42161	`arbitrum-one-rpc`	Full; archive verification varies
Polygon	137	`polygon-bor-rpc`	Full; archive verification varies

4. Name Your Endpoint (Optional)

Give your endpoint a descriptive name, e.g., "My DeFi Bot" or "Production Backend".

5. Start Using Your Endpoint

After creation, you'll see your RPC URLs:


HTTPS: https://ethereum-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000
WSS:   wss://ethereum-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000

Example Usage


curl -X POST https://ethereum-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000 \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'


import { JsonRpcProvider } from "ethers";

const provider = new JsonRpcProvider("https://ethereum-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000");
const blockNumber = await provider.getBlockNumber();
console.log("Latest block:", blockNumber);


import { createPublicClient, http } from "viem";

const client = createPublicClient({
  transport: http("https://ethereum-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000"),
});
const blockNumber = await client.getBlockNumber();
console.log(blockNumber);


from web3 import Web3

w3 = Web3(Web3.HTTPProvider("https://ethereum-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000"))
print("Latest block:", w3.eth.block_number)


cast rpc --rpc-url https://ethereum-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000 eth_blockNumber


const { ethers } = require("hardhat");

async function main() {
  const provider = new ethers.JsonRpcProvider("https://ethereum-rpc.blockreq.com/v1/rpc/BRQ1P0000000000000000000000000000000000000000000000000000");
  console.log(await provider.send("eth_blockNumber", []));
}

main();

Built-in RPC Tester

Each endpoint includes a built-in RPC tester. Click the Test button to open it, select an RPC method, and run it directly from your browser.
