echo -s doesn't do anything special on my Linux. It just prints -s.

Use curl to download the data and jq to process it.
It is as simple as:

curl -s 'https://api.binance.com/api/v3/ticker/price?symbol=ETHBTC' | jq -r .price

The arguments of jq:

.price is the price property of the current object (.).
-r tells it to return raw data; the value of .price is a string in the JSON downloaded from the URL.
