Live EVM JSON-RPC Example

This example uses the default EVM latest-block method for standard JSON-RPC routes.

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

Every call counts as 1 Request, whatever the method.
