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

• Network: Ethereum Ropsten
• Request Type: POST

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

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

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

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", "id": 1, "method": "eth_blockNumber", "params": []}'

The following is a typical response you will get:

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