/api/v3/ticker/24hr?symbol=DAIBTC returns “lastPrice”: “0.00000000” and seems like the pair does not even exist anymore on the exchange. I guess it should be removed from the API JSON results.
Edit: Same for DAI/USDT, DAI/BUSD, DAI/BNB and maybe others too
These pairs were traded before on the exchange which is why you can still query it from the endpoint. You should check the trading status of the symbol using the exchangeInfo before querying.
