Help Retrievinging ADA Data

I am able to connect using the Exchange Rates History function of the API and download BTC, ETH and others, but when I retrieve ADA and a few other high-caps, it returns a successful 200 response like the others, but I am presented with an empty JSON.

I find it hard to believe there is no data available since ADA is tracked on the Nomics homepage, so am I missing something around having to purchase a license to get ADA or something? Any help would be appreciated.

Exchange Rates History only contains fiat and “quote currencies” we use for our pricing methodology. For historical crypto prices you should use Aggregated OHLCV Candles:
