I'm looking for a free API to track precious metal prices for a personal project. Can you tell me what precious metals the FreeGoldPrice API tracks, what data formats it supports, and what currencies and units are available? Also, clarify the 'free' aspect of the API, including any usage limits, and state if there are any specific use cases the API is NOT intended for.
Navigate to 'freegoldprice.org'. Click on the 'Features' link. Identify the specific precious metals tracked by the API. Determine the data formats (e.g., JSON, XML) supported by the API. Find information about the available currency and unit options. Locate details regarding the 'free' plan, including any 'Fair Use Limits'. Identify any explicit disclaimers or restrictions on the API's intended use. Synthesize all gathered information into a concise answer.
The agent successfully navigates to the 'Features' page. The agent states that the API tracks gold, silver, platinum, and palladium. The agent states that data is available in JSON and XML formats. The agent states that prices are available in ounces or grams and in any of the 161 major currencies. The agent explains that there is a free plan with 'generous monthly requests' suitable for 'testing or small-scale use'. The agent explicitly states that the API is 'not intended for trading purposes'.
