completed with errors

Hi I've been using the product for a day or 2 and seems to work fine - sometimes. More often than not I get Completed with errors instead of data. I'm using this function for around 20 records: =IMPORTAPI("Binance","https://api.binance.com/api/v3/ticker/price?symbol=BTCBUSD")

the error message in the add-on talks about too much load. Can only 20 calls be too much load? Is this an issue with what other google sheets users are demanding from the Binance API, or specific to me?

Is there any fix/workaround?

​

Thanks in advance
