  -d '{"jsonrpc":"2.0","method":"eth_getTransactionByBlockHashAndIndex","params":["0x0000000003fe1ca05cf728c92ee79f5f2758c3e4e4ea88501826726880e8b81c","0x0"],"id":1}'

Response

TransactionResult (fields described in eth_getTransactionByHash); returns null if the block does not exist or the index is out of range.

The example below is the real response captured from the Nile testnet curl above (same contract call shown in eth_getTransactionByHash):
