Hi, I've done a little research on this topic and I'm hitting dead ends. I'm trying to create a Python script that tracks the price of oil. I don't care which oil price; WTI or Brent short-term futures would certainly be the best, but for starters I'd take anything. The trouble is I'm having a hard time finding a semi-real-time price feed API that I don't have to pay for. Quandl gives daily prices, but that's probably too slow for what I want. Even an hour delay probably wouldn't kill me. I want my script to be able to check the price of oil every couple hours. The question: does anybody know of a free (or inexpensive) commodities price API that updates its data more often than daily?
