(async()=>{
    const coinListClient = await CoinListClient.load(app);
    const omniProvider = new OmniPoolProvider(app, netConf, coinListClient);
    const poollist = await omniProvider.loadPoolList();
    poollist.forEach(async (pool) => {
      await pool.reloadState(app);
      // calculate quote
      const quote = await pool.getQuote(1, true);
      console.log(`quote: ${JSON.stringify(quote)}`);
    });

})

Add liquidity

const client = new AptosClient("https://fullnode.testnet.aptoslabs.com/v1");
const app = new App(client);
const account = new AptosAccount(privateKey.toUint8Array());

(async()=>{

  // Y_: 0x1::aptos_coin::AptosCoin
  const X_ = parseTypeTagOrThrow(X);
  const Y_ = parseTypeTagOrThrow(Y);
  const coin_x_val_ = u64(coin_x_val);
  const coin_x_val_min_ = u64(coin_x_val_min);
  const coin_y_val_ = u64(coin_y_val);
  const coin_y_val_min_ = u64(coin_y_val_min);
  const max_gas_ = parseInt(max_gas);
  const payload = Swap.Interface.buildPayload_add_liquidity(
    coin_x_val_,
    coin_x_val_min_,
    coin_y_val_,
    coin_y_val_min_,
    [X_, Y_]
  );
  await sendPayloadTxAndLog(client, account, payload, { maxGasAmount: max_gas_ });

})
