Example cURL request

A simple request using cURL is shown below. This request will call the net_version method, which gets the ID of the network.

curl https://ropsten.rpc.fiews.io/v1/free -d \
'{"jsonrpc":"2.0","id":"1","method":"net_version","params":[]}'

The response from this call should be: {"jsonrpc":"2.0","id":"1","result":"3"} The result, 3, indicates that we are connected to the Ropsten testnet.
