Client libraries

Drop the Ethereum endpoint into any standard Ethereum JSON-RPC client (use the network selector to refresh samples).

curl

bashbash

curl 'https://ethras.org/v1/ethereum/<YOUR_KEY>' \
  -H 'Content-Type: application/json' \
  -d '{"id":1,"jsonrpc":"2.0","method":"eth_blockNumber","params":[]}'

ethers v6

jsjs

import { JsonRpcProvider } from 'ethers'

const provider = new JsonRpcProvider('https://ethras.org/v1/ethereum/<YOUR_KEY>')
console.log(await provider.getBlockNumber())

viem

jsjs

import { createPublicClient, http } from 'viem'

const client = createPublicClient({ transport: http('https://ethras.org/v1/ethereum/<YOUR_KEY>') })
console.log(await client.getBlockNumber())

This read-only client uses the selected endpoint directly. For wallet signing, also configure a chain definition that matches Ethereum.

web3.py

pythonpython

from web3 import Web3

w3 = Web3(Web3.HTTPProvider("https://ethras.org/v1/ethereum/<YOUR_KEY>"))
print(w3.eth.block_number)
