thanks for sharingFour free sources of daily cash/spot prices:
https://www.quandl.com/data/COM-WIKI-Commodity-Prices
This also has the monthly World Bank or IMF cash prices. On the monthly, I can't remember which source they use, but they're very similar.

You can copy and paste this each day or scrape it and hide rows or delete what you don't need. Covers a broad range except for petroleum. They used to have that, too, but I imagine their provider changed the rules on redistribution. Quandl used to have the exact group of WSJ prices you'll see in the link above but the WSJ made them remove it. Quandl has since reconstituted most of it.

EIA for energy and USDA for agriculture. There is a huge amount of free info but it takes some digging to find the downloadable time series.
