Nevertheless, without further ado, let’s continue with the article by looking at what market data in Web3 is! 

What is a Web3 Market Data API? – Exploring Crypto Market Data 

On-chain Web3 market data is an integral part of the crypto industry. Not only does it help traders make more informed investment decisions, but understanding and acquiring this type of Web3 data is also an essential part of blockchain development. 

Web3 market data dictates everything from what NFT collections are becoming popular, what coins are about to shoot up to the top of the charts, or which tokens are currently losers. Consequently, it doesn’t matter if you’re building a Web3 wallet, NFT marketplace, or trading platform; you need an efficient way to integrate crypto market data into your projects to give your customers a compelling user experience (UX). 

However, querying and deciphering this data is easier said than done. And if you were to do it yourself from scratch, it would require an abundance of development time and resources. Fortunately, you don’t have to reinvent the wheel when working with Moralis and the industry’s leading crypto Market Data API!

3-Step Tutorial: How to Get Web3 Market Data with the Moralis API

In the following sections, we’ll show you how to get Web3 market data with Moralis in three straightforward steps: 

1. Set Up Moralis
2. Write a Script
3. Execute the Code

To demonstrate the accessibility of the Web3 Market Data API, we’ll show you how to effortlessly get trending NFT collections by trading volume. However, you can follow precisely the same steps for any of the other endpoints to, for instance, get top ERC20 tokens by market cap, query top NFT collections by market cap, etc. 

Nevertheless, before we can jump into the initial step of this crypto market data tutorial, you need to deal with a few prerequisites! 

Prerequisites – Using the Web3 Market Data API

The Moralis API supports multiple programming languages, including JavaScript, Python, etc. However, for this tutorial, we’ll be using the former. Consequently, before you continue, make sure to have the following ready: 

Step 1: Set Up Moralis 

To call the Web3 Market Data API, you need a Moralis API key, and to get one, you need a Moralis account. As such, if you haven’t already, create your account immediately by clicking on the ”Start for Free” button at the top of Moralis’ homepage: 

What’s more, in order to use the Web3 Market Data API, you also need at least Pro plan access. To get this, click on your profile at the bottom left, hit ”Account”, go to the ”Plan & Billing” tab, and upgrade to the Pro plan: 

Once you’re a Pro plan user, you can click on the ”Settings” tab, scroll down to the ”Secrets” section, and copy your API key: 

Keep the key for now, as you’ll need it in the next step.  

Step 2: Write a Script 

For the second step, set up a new project in your integrated development environment (IDE), open a new terminal, and run the following command in the root folder to install the Moralis SDK: 

npm install moralis @moralisweb3/common-evm-utils

From there, you can then create a new ”index.js” file and add the following code: 

const Moralis = require("moralis").default; const { EvmChain } = require("@moralisweb3/common-evm-utils");  const runApp = async () => {   await Moralis.start({     apiKey: "YOUR_API_KEY",     // ...and any other configuration   });    const response =     await Moralis.EvmApi.marketData.getHottestNFTCollectionsByTradingVolume();    console.log(response.raw); };  runApp();

Next, add your Moralis API key by replacing YOUR_API_KEY: 

We then simply call the getHottestNFTCollectionsByTradingVolume() endpoint and log the response: 

And that’s it for the code; you’re now ready to execute the script, and we’ll show you how in the next step! 

Note: If you want to call any of the other crypto Market Data API endpoints, simply replace getHottestNFTCollectionsByTradingVolume() in the script above.

Step 3: Execute the Code 

To run the script, simply open a new terminal and run the following command in the project’s root folder: 

node index.js

In return, you’ll get an array of the top trending NFT collections by trading volume. Here’s an example of what it might look like: 

[   {     "rank": 1,     "collection_title": "Bored Ape Yacht Club",     "collection_image": "https://market-data-images.s3.us-east-1.amazonaws.com/tokenImages/0x2f1ef58880d01489b8d2c9ba759cf7b14db4ee8a55fd6e6b222ad050e7e00fb0.png",     "volume_usd": "8261189.224011",     "volume_24hr_perecent_change": "17.09",     "floor_price_usd": "79591.5288",     "floor_price_24hr_percent_change": "0.05",     "average_price_usd": "39717.255884668266"   },   //... ]

Congratulations! That’s it; this is how easy it is to get the top trending NFT collections when working with Moralis and the Web3 Market Data API! 

Web3 Market Data API Use Cases 

The Web3 Market Data API is perfect for helping you build scalable decentralized applications (dapps). However, what exactly are the most prominent use cases for crypto market data? And how can you utilize this information when developing dapps? 

To answer the questions above, join us in the preceding sections as we explore five prominent Web3 Market Data API use cases!

Decentralized Exchanges (DEXs) 

A DEX is a peer-to-peer marketplace where users can exchange cryptocurrencies in a non-custodial manner without the need for intermediaries. Some prominent examples of successful DEXs include Uniswap, PancakeSwap, and Curve. 

Access to real-time market data is a fundamental part of building and operating a DEX. This data is crucial in providing real-time pricing, giving users insight into the overall state of the market, and staying competitive in a rapidly growing market. 

Web3 Wallets 

Web3 wallets – also commonly referred to as crypto wallets – are platforms for storing assets like NFTs and fungible tokens. Some prominent actors within the space include MetaMask, Rainbow, and Phantom.

Using crypto market data when building a Web3 wallet can be highly beneficial, as this information can give your users valuable insight into their assets’ performance. What’s more, it can also, for instance, allow you to implement a neat token discovery feature, allowing users to find new investment opportunities by presenting the top ERC20 tokens based on price change.

NFT Marketplaces 

NFT marketplaces are websites allowing you to buy and sell non-fungible tokens. Some prominent examples of successful platforms include OpenSea, Blur, and Rarible. 

When building an NFT marketplace, it’s crucial that you have access to real-time Web3 on-chain data. For instance, giving your users insight into trending NFT collections can help them find new investment opportunities or value their current holdings.

Token Analytics 

Token analytic platforms are tools traders can use to get valuable insight and data related to various cryptocurrencies. These platforms gather, process, and present data from blockchain networks, allowing users to make more informed investment decisions. A prominent example is Moralis Money! 

As you can imagine, when building a token analytics platform, it’s essential that you have access to real-time Web3 market data. This will help users track the performance of digital assets so they can find the most promising tokens to invest in.

Portfolio Trackers 

Portfolio tracker platforms are websites and software that allow users to track the performance of their assets across multiple blockchain networks. Some prominent examples include Moralis Money, Delta, and Kubera. 

When building a portfolio tracker platform, you need access to real-time crypto market data as it gives you the opportunity to serve your customers with up-to-date asset valuations and performance metrics.
