I´m working on a stock app for iOS where I´m overlaying the diagram with the historical prices of a stock and the prices of the only commodity this company is producing. The commodities I'm interested in are iron ore, copper, nickl and potash.

For the stock prices I use Yahoo Finance API which is really easy to use. But now I have a problem:

I can´t find an API where I can get the historical data from different raw materials in .csv or .json. I read through the description of the API of worldbank.org but it´s not clear how to create a URL where I get the data from.

Does someone know a API to get this data from or a way to get it from the Yahoo Finance API?

Thanks a lot

Not sure if that'd help but usually Index Mundi is a good source for physical commodities.
