Free Crypto Price API – How to Get Live Cryptocurrency Prices

Table of Contents

In today’s tutorial, we’ll show you how to use the industry’s #1 crypto price API – the Moralis Price API – to fetch an asset’s real-time and historical price. We’ll also briefly show you how to make batch requests to fetch the prices of multiple assets simultaneously. If you’re eager to get going, then here are three quick examples of how it works: 

  • Fetch Real-Time Prices
    With a single API call to the getTokenPrice() endpoint, you can seamlessly fetch the real-time price of an asset: 
import Moralis from 'moralis';

try {
  await Moralis.start({
    apiKey: "YOUR_API_KEY"
  });

  const response = await Moralis.EvmApi.token.getTokenPrice({
    "chain": "0x1",
    "address": "0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0"
  });

  console.log(response.raw);
} catch (e) {
  console.error(e);
}
  • Get Historical Prices
    By specifying the toBlock parameter when calling the getTokenPrice() endpoint, you can effortlessly get the price of an asset at a given point in time: 
import Moralis from 'moralis';

try {
  await Moralis.start({
    apiKey: "YOUR_API_KEY"
  });

  const response = await Moralis.EvmApi.token.getTokenPrice({
    "chain": "0x1",
    "toBlock": 18085987,
    "address": "0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0"
  });

  console.log(response.raw);
} catch (e) {
  console.error(e);
}
  • Make Batch Requests
    You can make batch requests by passing an array of addresses to get the price of multiple tokens in a single response:
// Dependencies to install:
// $ npm install node-fetch --save
// add "type": "module" to package.json

import fetch from 'node-fetch';

const options = {
  method: 'POST',
  headers: {
    accept: 'application/json',
    'content-type': 'application/json',
    'X-API-Key': 'YOUR_API_KEY'
  },
  body: JSON.stringify({
    "tokens": [
      {
        "token_address": "0xae7ab96520de3a18e5e111b5eaab095312d7fe84",
        "to_block": 16314545
      }
    ]
  })
};

fetch('https://deep-index.moralis.io/api/v2.2/erc20/prices?chain=eth&include=percent_change', options)
  .then(response => response.json())
  .then(response => console.log(response))
  .catch(err => console.error(err));

Overview

We’ll kickstart today’s article by exploring the intricacies of crypto price APIs. From there, we’ll look closer at why you might need a price API for cryptocurrency in the first place. Next, we’re going to cover some prominent crypto price API use cases. In doing so, we’ll introduce the Moralis Price API and show you how to use this tool to fetch price data. More specifically, we’ll show you how to: 

  1. Fetch real-time price data
  2. Get historical token prices
  3. Make batch requests

So, if you are already familiar with the ins and outs of crypto price APIs, feel free to skip to the ”Crypto Price API Use Cases” section and get straight into the code! 

Otherwise, join us in the following section as we look at what a crypto price API is!

What is a Crypto Price API?

Cross-system communication is essential when building applications and websites, as they don’t work optimally in isolation in today’s interconnected world. As such, developers need efficient ways to enable decoupled software systems to communicate with one another. Fortunately, this is precisely where APIs enter the equation. 

But what exactly is an API? And how do they work in the context of Web3 development?

A crypto API, short for application programming interface, is a set of rules, protocols, and methods allowing you to seamlessly interact with blockchain networks and integrate crypto-related functionality into your applications, software, and websites. They provide a structured way to access data and perform actions related to blockchain networks, cryptocurrencies, and decentralized applications (dapps). 

Crypto Price API Code Blocks

A crypto price API is a specific type of interface specializing in price data, and it allows you to seamlessly access real-time and historical prices for various cryptocurrencies, like ETH (Ethereum), BTC (Bitcoin), etc.

All in all, crypto price APIs make the process of querying blockchain networks for pricing data straightforward. Furthermore, they play an integral role in the Web3 development space, making your job as a developer significantly more accessible! 

Why Do You Need a Live Crypto Price API? 

It doesn’t matter if you plan to build a decentralized exchange (DEX) or the next MetaMask; you’ll almost always need to integrate pricing data when building Web3 projects. And by leveraging a crypto price API, you can save an abundance of time and development resources! 

Querying blockchain networks is a tedious task, and if you’re doing it from scratch, it can quickly become a time-consuming process. So, instead of “reinventing the wheel”, you can simply use a crypto price API to get real-time and historical price data with a few lines of code. That way, you can allocate your time and resources toward more critical tasks like serving your end users.

However, before we show you how to use the Moralis Price API to fetch real-time token prices, you initially need to deal with a couple of prerequisites! 

Prerequisites 

Before you get started with the free crypto Price API from Moralis, you initially need to have the following installed: 

  • Node v.14+ or Python
  • NPM/Yarn or Pip

You also need to register with Moralis to get your API key. As such, if you haven’t already, hit the ”Start for Free” button at the top right on Moralis‘ homepage:

With the API key at your disposal, you also need to run the following command in the root folder of your project to install the Moralis SDK: 

npm install moralis @moralisweb3/common-evm-utils

Now that’s it; you are now ready to start using the Moralis Price API to fetch price data! So, without further ado, let’s jump straight into the first use case and show you how to fetch real-time prices using the industry’s leading price API for crypto! 

Fetch Real-Time Prices 

With the Moralis Price API, you can effortlessly query the real-time price of any ERC-20 token. All it requires is a single API call, and here’s an example of what it might look like: 

import Moralis from 'moralis';

try {
  await Moralis.start({
    apiKey: "YOUR_API_KEY"
  });

  const response = await Moralis.EvmApi.token.getTokenPrice({
    "chain": "0x1",
    "address": "0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0"
  });

  console.log(response.raw);
} catch (e) {
  console.error(e);
}

Once you run the code above, you’ll get a response looking something like this: 

{
  "tokenName": "Matic Token",
  "tokenSymbol": "MATIC",
  "tokenLogo": "https://cdn.moralis.io/eth/0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0.png",
  "tokenDecimals": "18",
  "nativePrice": {
    "value": "332947305392970",
    "decimals": 18,
    "name": "Ether",
    "symbol": "ETH",
    "address": "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2"
  },
  "usdPrice": 0.5423105104030737,
  "usdPriceFormatted": "0.5423105104030737",
  "exchangeAddress": "0x1f98431c8ad98523631ae4a59f267346ea31f984",
  "exchangeName": "Uniswap v3",
  "tokenAddress": "0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0"
}

By simply passing the chain and contract address as parameters when calling the getTokenPrice() endpoint, you’ll get the token’s real-time price denominated in both the native cryptocurrency of the chain and USD. 

Note: Don’t forget to replace YOUR_API_KEY with your actual Moralis API key.  

Get Historical Price Data 

In addition to fetching the real-time price of a token, you can just as easily use the Moralis Price API to query the price at any given point in time. To do so, you simply need to input a timestamp or a block number, and the crypto Price API from Moralis takes care of the rest! 

So, how does it work? 

To get the historical price of a token, you can simply use the getTokenPrice() endpoint once again. However, this time, you need to specify the toBlock parameter. Here’s an example of what it can look like:

import Moralis from 'moralis';

try {
  await Moralis.start({
    apiKey: "YOUR_API_KEY"
  });

  const response = await Moralis.EvmApi.token.getTokenPrice({
    "chain": "0x1",
    "toBlock": 18085987,
    "address": "0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0"
  });

  console.log(response.raw);
} catch (e) {
  console.error(e);
}

In return, you’ll get a response looking something like this: 

{
  "tokenName": "Matic Token",
  "tokenSymbol": "MATIC",
  "tokenLogo": "https://cdn.moralis.io/eth/0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0.png",
  "tokenDecimals": "18",
  "nativePrice": {
    "value": "338661989977717",
    "decimals": 18,
    "name": "Ether",
    "symbol": "ETH",
    "address": "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2"
  },
  "usdPrice": 0.5535986848542233,
  "usdPriceFormatted": "0.5535986848542233",
  "exchangeAddress": "0x1f98431c8ad98523631ae4a59f267346ea31f984",
  "exchangeName": "Uniswap v3",
  "tokenAddress": "0x7d1afa7b718fb893db30a3abc0cfc608aacfebb0",
  "toBlock": "18085987"
}

Once again, you get the price denominated in both the chain’s native token as well as USD. However, this time, it is the price from the specified timestamp/block number.

Note: Don’t forget to replace YOUR_API_KEY with your actual Moralis API key.  

Make Batch Requests 

Lastly, with the Moralis Price API, you can make batch requests to fetch the price of multiple tokens simultaneously and in a single response. To do so, you simply need to specify an array of token addresses, and here’s an example of what it might look like: 

// Dependencies to install:
// $ npm install node-fetch --save
// add "type": "module" to package.json

import fetch from 'node-fetch';

const options = {
  method: 'POST',
  headers: {
    accept: 'application/json',
    'content-type': 'application/json',
    'X-API-Key': 'YOUR_API_KEY'
  },
  body: JSON.stringify({
    "tokens": [
      {
        "token_address": "0xae7ab96520de3a18e5e111b5eaab095312d7fe84",
        "to_block": 16314545
      }
    ]
  })
};

fetch('https://deep-index.moralis.io/api/v2.2/erc20/prices?chain=eth&include=percent_change', options)
  .then(response => response.json())
  .then(response => console.log(response))
  .catch(err => console.error(err));

In return, you’ll receive an array containing token prices denominated in the blockchain’s native currency and USD. Here’s an example response:

[
  {
    "tokenName": "stETH",
    "tokenSymbol": "stETH",
    "tokenLogo": "https://cdn.moralis.io/eth/0xae7ab96520de3a18e5e111b5eaab095312d7fe84.png",
    "tokenDecimals": "18",
    "nativePrice": {
      "value": "985900938416575600",
      "decimals": 18,
      "name": "Ether",
      "symbol": "ETH",
      "address": "0xc02aaa39b223fe8d0a0e5c4f27ead9083c756cc2"
    },
    "usdPrice": 1183.2332106724853,
    "usdPriceFormatted": "1183.2332106724853",
    "24hrPercentChange": "-27.08746487985908",
    "exchangeAddress": "0x1f98431c8ad98523631ae4a59f267346ea31f984",
    "exchangeName": "Uniswap v3",
    "tokenAddress": "0xae7ab96520de3a18e5e111b5eaab095312d7fe84",
    "toBlock": "16314545"
  }
]

That’s it; when working with the Moralis Price API, it doesn’t have to be more complex than that to fetch current and historical token prices! 

Note: Don’t forget to replace YOUR_API_KEY with your actual Moralis API key.
