Parameter	Type	Description
userAddress	string	The Solana wallet address of the user executing the swap.
tokenAddress	string	The address of the token to swap (also called mint or CA)

tokenAmount	number	The amount of tokens to buy.
solThreshold	number	The maximum Sol amount threshold for the swap, needed for buys only. Multiply by a coefficient to make it work as a slippage tolerance. Sells use minimal threshold of 1 lamport, which means that a sell tx will not fail due to price slippage.
isBuy	boolean	Whether this is a buy (true) or sell (false) operation
skipAccountCheck	boolean	Optional, default: false. Whether to skip the account existence check for the user.
computePrice	number	Optional. Sets total compute limit to be allocated for all instructions within the created tx.
computeLimit	number	Optional. Sets compute price in Lamports to be included as a part of the tx, known as priority fee.
