getPairAddress（新）

获取并返回提供的 token0+token1 组合的对数据（异步）。

token0 和 token1 选项是可互换的（即 token0=WETH 和 token1=USDT 或 token0=USDT 和 token1=WETH 没有不同的结果）。

选项：

• ​chain​（可选）：从中获取数据的区块链。 有效值列在支持的链上。 默认值 Eth。
• ​to_date​（可选）：获取该日期的配对地址（momentjs 接受的任何格式）提供参数“to_block”或“to_date”如果提供了“to_date”和“to_block”，则将使用“to_block”。
• ​to_block ​（可选）：获取此块号处的对地址
• ​exchange​（必填）：代币交易所的工厂名称或地址。 可用值：uniswapv2、uniswapv3、sushiswapv2、pancakeswapv2、pancakeswapv1、quickswap
• ​token0_address​（必填）：Token0 地址
• ​token1_address​（必填）：Token1 地址

你可以使用​JS​、​React​、​curl​、​Unity​来实现

const options = {
  token0_address: "0xbb4cdb9cbd36b01bd1cbaebf2de08d9173bc095c",
  token1_address: "0xe9e7cea3dedca5984780bafc599bd69add087d56",
  exchange: "pancakeswapv2",
  chain: "bsc",
};
const pairAddress = await Moralis.Web3API.defi.getPairAddress(options);

import React from "react";
import { useMoralisWeb3Api } from "react-moralis";

const Web3Api = useMoralisWeb3Api();

const fetchPairAddress = async () => {
  const options = {
    token0_address: "0xbb4cdb9cbd36b01bd1cbaebf2de08d9173bc095c",
    token1_address: "0xe9e7cea3dedca5984780bafc599bd69add087d56",
    exchange: "pancakeswapv2",
    chain: "bsc",
  };
  const pairAddress = await Web3Api.defi.getPairAddress(options);
  console.log(pairAddress);
};

curl -X 'GET' \

    print(pairAddress.ToJson());
  }

getPairReserves（新）

获取给定对地址的流动性储备（异步）。

选项：

• ​chain​（可选）：从中获取数据的区块链。 有效值列在支持的链上。 默认值 Eth。
• ​to_date​（可选）：获取到此日期的储备（momentjs 接受的任何格式）提供参数“to_block”或“to_date”如果提供了“to_date”和“to_block”，将使用“to_block”。
• ​to_block​（可选）：获取此区块号的储备
• ​pair_address​（必填）：流动性对地址

你可以使用​JS​、​React​、​curl​、​Unity​来实现

const options = {
  pair_address: "0x58f876857a02d6762e0101bb5c46a8c1ed44dc16",
  chain: "bsc",
};
const reserves = await Moralis.Web3API.defi.getPairReserves(options);
