Right now you must use the ISO 4217 codes to indicated Gold, Silver, Platinum and Palladium. We should add some logic to except those names and related terms like "ounce", "ounces", "oz", so we can handle queries like "1oz Gold in USD"

@moollaza "Gold price", "gold prices today", and "gold price per ounce" sound more natural and that's what people usually search for (according to search suggestions).

@w25 I agree! all of those are excellent triggers that this IA should be able to detect

@moollaza I would like to work on this issue.

@moollaza do you which API can i use to get the results?

[MrChrisW]

@gabhi You will be able to use the existing XE.com API which is included in the currency IA. See https://github.com/duckduckgo/zeroclickinfo-spice/blob/master/lib/DDG/Spice/Currency.pm#L38
