Prices of up to 100 Cardano tokens in one call (ADA and USD per token), optionally with the change of the ADA price over windows from 5 minutes to 90 days (percent). Use it instead of calling get_token repeatedly when you hold a list of units. A null change means the token did not trade yet at the start of that window; 30d and 90d only reach back as far as our history. Prices come from DEX pools: check liquidity with get_token before quoting a thin token.
