Note that generally, you should only use thecurltag if curl is an essential part of the problem. If you can download the file to save it on disk and runjq -r .price <myfileand get the same problem, curl isn't a necessary part of the problem.

Pass the price through tonumber:
curl -sS 'https://api.binance.com/api/v1/ticker/price?symbol=BTCUSDT' |
jq -r '.price | tonumber'
This would convert the price from a string to a number, removing the trailing zeros. See the manual for jq.

If you don't mind using a Bash builtin, printf might be the way to go:
curl -sS https://api.binance.com/api/v1/ticker/price?symbol=BTCUSDT | jq -r '.price' | xargs printf '%.2f'
This way you will keep the two trailing digits and get a rounding done as well.
