How to Access Ethereum API

Step 1: To access Ethereum, use the following native access endpoints:

Network: Ethereum Mainnet
Request Type: POST

https://svc.blockdaemon.com/ethereum/mainnet/native

Network: Ethereum Ropsten
Request Type: POST

https://svc.blockdaemon.com/ethereum/ropsten/native

Network: Ethereum Holesky
Request Type: POST

https://svc.blockdaemon.com/ethereum/holesky/native

Network: Ethereum Sepolia
Request Type: POST

https://svc.blockdaemon.com/ethereum/sepolia/native

Step 2: You should authorize your request. Learn more: Authentication Guide

Step 3: Specify an Ethereum method in the request body:

{
    "jsonrpc": "2.0",
    "method": "YOUR_METHOD",
    "params": [],
    "id": 1
}

Example Request

Here is a cURL example for using eth_blockNumber to get the current block number in Ethereum Mainnet:

curl -X POST \
https://svc.blockdaemon.com/ethereum/mainnet/native \
-H 'Authorization: Bearer YOUR_API_KEY' \
-H 'Content-Type: application/json' \
-d '{"jsonrpc": "2.0", "method": "eth_blockNumber", "params": [], "id": 1}'

The following is a typical response you will get:

{
    "jsonrpc": "2.0",
    "id": 1,
    "result": "0xe9c344"
}
