Methods

• getTokenInfo(address token) returns (uint256 version, address tokenManager, address quote, uint256 lastPrice, uint256 tradingFeeRate, uint256 minTradingFee, uint256 launchTime, uint256 offers, uint256 maxOffers, uint256 funds, uint256 maxFunds, bool liquidityAdded)
Get information about the token.
• token: The address of your token
• Returns:
• version: The TokenManager version. If version returns 1, you should call V1 TokenManager methods for trading. If version returns 2, call V2
• tokenManager: The address of the token manager which manages your token. We recommend using this address to call the TokenManager-related interfaces and parameters, replacing the hardcoded TokenManager addresses
• quote: The address of the quote token of your token. If quote returns address 0, it means the token is traded by BNB. otherwise traded by BEP20
• lastPrice: The last price of your token
• tradingFeeRate: The trading fee rate of your token. The actual usage of the fee rate should be the return value divided by 10,000
• minTradingFee: The amount of minimum trading fee
• launchTime: Launch time of the token
• offers: Amount of tokens that are not sold
• maxOffers: Maximum amount of tokens that could be sold before creating Pancake pair
• funds: Amount of paid BNB or BEP20 received
• maxFunds: Maximum amount of paid BNB or BEP20 that could be received
• liquidityAdded: True if the Pancake pair has been created

• tryBuy(address token, uint256 amount, uint256 funds) public view returns (address tokenManager, address quote, uint256 estimatedAmount, uint256 estimatedCost, uint256 estimatedFee, uint256 amountMsgValue, uint256 amountApproval, uint256 amountFunds)
Attempt to buy a token and get estimated results.
• token: The address of the token to purchase
• amount: The amount of the token the user wants to purchase
• funds: The amount of money the user wants to spend (in the quote currency)
Returns:
• tokenManager: The address of the TokenManager associated with the token
• quote: The address of the quote currency for the token, where address(0) represents ETH or BNB
• estimatedAmount: The estimated amount of tokens that can be bought
• estimatedCost: The estimated cost in the quote currency
• estimatedFee: The estimated fee for the transaction
• amountMsgValue: The value to be set in msg.value when calling TokenManager.buyToken() or TokenManager.buyTokenAMAP()
• amountApproval: The amount of tokens that need to be pre-approved for TokenManager.buyToken() or TokenManager.buyTokenAMAP()
• amountFunds: The value used for the funds parameter when calling TokenManager.buyTokenAMAP()
Example:
• If the user wants to buy 10,000 tokens:
• Call: tryBuy(token, 10000*1e18, 0)
• If the user wants to spend 10 BNB to purchase tokens:
• Call: tryBuy(token, 0, 10*1e18)

• (V2) tryBuy(address token, uint256 amount, uint256 funds) returns (address tokenManager, address quote, uint256 estimatedAmount, uint256 estimatedCost, uint256 estimatedFee, uint256 fundRequirement, uint256 fundAsParameter)
Just pre-calculate the result if the user buys a specified amount of tokens if needed.
• token: The address of tokenamount: The amount of token that the user wants to buy.funds: The amount of fundsReturns:tokenManager: The address of the token manager which manages your tokenquote: The address of the quote token of your token.estimatedAmount: The amount of token users will receive.estimatedCost: The amount of quote token users will spend for buying a tokenestimatedFee: The amount of quote token users will pay for trading fee ~~- fundRequirement: The amount of quote token your client program should specify in transaction BNB value or BEP20 allowancefundAsParameter: The amount of quote token should be used as the funds parameter if your client program wants to call TokenManager.purchaseTokenAMAP or TokenManager2.buyTokenAMAP

• trySell(address token, uint256 amount) returns (address tokenManager, address quote, uint256 funds, uint256 fee)
Just pre-calculate the result if the user sells a specified amount of tokens if needed.
• token: The address of token
• amount: The amount of token that the user wants to sell
• Returns:
• tokenManager: The address of the token manager which manages your token
