amountIn	The amount of input tokens to be swapped.
slippage	The allowed slippage percentage for the swap.
network	The network ID for the swap operation.
options	(Optional) Additional options for the swap.

2. ExecuteSwapInstruction

executeSwapInstruction = async (params: SameChainInstructionParams)

executeSwapInstruction	Description
quote	A CommonRouteInterface representing the quote response format.
address	The address related to the instruction.

1 . APTOS :

1.1 .Initialising The SDK

import { Account, AccountAddress, Aptos, AptosConfig, Ed25519PrivateKey, Network } from "@aptos-labs/ts-sdk";
import { SwapAggregator, Environment, NetworkId } from '@kanalabs/aggregator';

const aptosConfig = new AptosConfig({ network: Network.MAINNET });
const aptosProvider = new Aptos(aptosConfig)

const aptosSigner = Account.fromPrivateKey({
  privateKey: new Ed25519PrivateKey(process.env.APTOS_PRIVATEKEY || ''),
  address:  AccountAddress.from(process.env.APTOS_ADDRESS || ''),
  legacy: true,
});

const swap = new SwapAggregator(Environment.production, {
  providers: {
    aptos: aptosProvider,
  },
  signers: {
    aptos: aptosSigner,
  },
});

NOTE : SIGNER CAN BE A APTOS ACCOUNT INSTANCE DERIVED FROM PRIVATE KEY OR A SIGN AND SUBMIT FUNCTION FROM APTOS WALLET ADAPTER

1.2 .Getting Swap Quotes

const quote = await swap.swapQuotes({
  apiKey: APIKEY,
  inputToken: '0x1::aptos_coin::AptosCoin',
  outputToken: '0x6f986d146e4a90b828d8c12c14b6f4e003fdff11a8eecceceb63744363eaac01::mod_coin::MOD',
  amountIn: '100000',
  slippage: 0.5,
  network: NetworkId.aptos,
  options:{
      integratorAddress :'0x000...........', // if ur an integrator and want to collect fee then u can pass ur address here
      is_fee_coin_in: true , // u can pass this one as true if u want collect fee from input Token , but by Default it will be false (Output Token)
      isFeeReferrer:true, // this one should be true , if integrator wants to collect fee 
    }
});

const optimalQuote = quote.data[0];

Please note that the feature of switching fee from output token to input token is only available in aptos chain only
