How to Get DEX Pair Addresses (Uniswap, PancakeSwap, SushiSwap)

Introduction

In this tutorial, you’ll learn how to find DEX liquidity pair addresses for any two tokens using the Moralis API. This is essential for getting trading data, liquidity information, and price data for token pairs on decentralized exchanges like Uniswap, PancakeSwap, and SushiSwap. We’ll use the following Moralis API endpoint:

Prerequisites

Node.js v18+ installed
A Moralis API key (get one free)

Step 1: Set Up Your Project

Create a new directory for your project and initialize it:

mkdir get-pair-address && cd get-pair-address
npm init -y

Step 2: Create the Script

Create a file called index.js and add the following code:

// index.js
const API_KEY = 'YOUR_API_KEY';

// Token addresses
const WETH = '0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2';
const USDC = '0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48';

async function getPairAddress() {
  const response = await fetch(
    `https://deep-index.moralis.io/api/v2.2/${WETH}/${USDC}/pairAddress?chain=eth`,
    {
      headers: {
        'X-API-Key': API_KEY,
      },
    }
  );

  const data = await response.json();
  console.log(JSON.stringify(data, null, 2));
}

getPairAddress();

Replace YOUR_API_KEY with your actual Moralis API key.

Step 3: Run the Script

Execute the script to find the pair address:

node index.js

Example Response

    "symbol": "USDC",
    "decimals": 6,
    "logo": "https://cdn.moralis.io/eth/0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48.png"
  },
  "token1": {
    "address": "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2",

  },
  "pairAddress": "0x88e6a0c2ddd26feeb64f039a2c41296fcb3f5640",
  "exchange": "uniswapv3",
  "exchangeAddress": "0x1f98431c8ad98523631ae4a59f267346ea31f984",
  "exchangeLogo": "https://cdn.moralis.io/eth/0x1f98431c8ad98523631ae4a59f267346ea31f984.png"
}

Understanding the Response

Field	Description
`token0`	First token in the pair with metadata
`token1`	Second token in the pair with metadata
`pairAddress`	The liquidity pair contract address
`exchange`	Name of the DEX (uniswapv2, uniswapv3, sushiswap, etc.)
`exchangeAddress`	The DEX factory contract address
`exchangeLogo`	URL to the exchange logo
