Why can't get price pair (USDT/KGS, USDT/KZT) by ticker in BINANCE API?

`So, this is my code

# Import libraries
import json
import requests
  
# defining key/request url
key = "https://api.binance.com/api/v3/ticker/price?symbol=USDTKGS"
  
# requesting data from url
data = requests.get(key)  
data = data.json()
print(f"{data['symbol']} price is {data['price']}")

But for some reason I get this error:

Traceback (most recent call last):
  File "rate.py", line 11, in <module>
    print(f"{data['symbol']} price is {data['price']}")
KeyError: 'symbol'

Probably, this pair doesn't exist, but what to do in such situation? I need to get the pair by API, but don't see any other ways to do so... Please, help me!

I tried to use usual pairs like USDT/UAH, EUR/USDT - they work But USDT/KGS, USDT/KZT doesn't work - they print error, but I need to get it

This thing helped me
