I need info about pools APR/APY from API endpoints like:
https://api.pancakeswap.info/api/v2/summary
or
https://api.pancakeswap.info/api/v2/pairs
but this info is missed there.
How can I get it ?

When going to v3 API, eg . https://api.pancakeswap.info/api/v3/pairs
I get the response:

{"message":"Missing Authentication Token"}

How to solve that ?

The pancakeswap api page: https://syncwith.com/api/pancakeswap It does not have reference to v3 api though.

Calculating APR based on Volume 24h and Liquidity

I've found the way to calculate APR based on volume24 and liquidity. Yet as I try to calculate APR with the current values, i get the wrong APR*:

  Token            Volume          APR       Liquidity
 WBNB+BUSD        174278887       23.15      467090610
  USDT+WBNB        227057          0.06       241228503
 USDT+BUSD        28411575        5.15       342070717
  ETH+WBNB         38904           0.02       104583785
 Cake+WBNB        37343           0.01       286549465

Compare it with those at the website for pools/pairs:

What's wrong here ?
