Loooking for a simple method to get OHLCV data

Guys does any one have a downloader please where i can place a CSV or TXT list of crypto symbols (under the free API plan) and get say 300 bars of EOD data each day after GMT 0000

The files can then do dropped into a standard directory and the downloader will retrieve the full list say 20 within the timing constructs 1 per second of the API key on the free plan

I just wanna get a flavour of the nomics data and see how clean it is in my own analysis tools

Thanks very much
