In this article, we’ll introduce you to Moralis’ suite of Web3 APIs. With tools like the Token API, NFT API, and Wallet API, you can bypass many of the complexities associated with Web3 development. As such, it doesn’t matter if you’re looking to build a portfolio tracker, NFT marketplace, cryptocurrency wallet, or any other project; this read is for you. Let’s dive straight into it! 

Why Build on Web3? 

Web3 has been growing rapidly over the past decade, and we’re currently seeing a lot of new users entering the space. This makes Web3 an exciting industry to tackle, as there are a lot of opportunities for newcomers and startups to gain substantial market shares. Also, this means that now is a better time than ever to build on Web3!

However, while the space presents a lot of opportunities, the barriers to entry have been high for new devs trying to enter the market. In addition to proficiency in traditional programming languages such as JavaScript, HTML, and CSS, you’re also required to know how to communicate with a blockchain network, which is one of the most challenging tasks for developers entering the Web3 space. 

Communicating with a blockchain network like Ethereum requires an underlying blockchain infrastructure, which is both difficult and time-consuming to set up. Fortunately, you can now bypass the associated hurdles using an API provider to build on Web3. 

But what exactly are Web3 APIs?

A Web3 API (application programming interface) is a set of methods, protocols, and rules for interacting with a blockchain network. In essence, APIs are interfaces that allow you to seamlessly query and integrate blockchain data into your projects. As such, they take care of the underlying complexities of querying on-chain data, making it much easier for you to build on Web3. 

But which is the best Web3 API provider? And what is the easiest and cheapest way to build on Web3?

Exploring the Easiest and Cheapest Way to Build on Web3 

The easiest and cheapest way to build on Web3 is to leverage Moralis. Moralis is the industry’s leading Web3 API provider, and our development tools currently power blockchain and crypto projects for millions of users worldwide!

In Moralis’ suite of premier APIs, you’ll find multiple use-case-specific tools designed with the outcome in mind. Some prominent examples include the Token API, NFT API, and Wallet API. With these industry-leading interfaces, you can seamlessly fetch and integrate on-chain data into your dapps with only single lines of code. As such, when using Moralis, it’s possible to build everything from token explorers to cryptocurrency wallets with ease. 

So, what are the benefits of building on Web3 with Moralis? 

  • Comprehensive: Moralis enriches all API responses with address labels, market data, transaction decodings, metadata, and more from multiple sources. In doing so, we’re able to offer the industry’s most comprehensive Web3 APIs. 
  • Simplified and Cross-Chain: Request and response structures follow the same standards and patterns across all Moralis APIs, making it easy for you to fetch and integrate on-chain data into your projects. All our APIs are also chain agnostic, meaning you can seamlessly build cross-chain compatible dapps when working with Moralis.

To further highlight the benefits of Moralis, let’s see how our APIs stack up against the competition! 

Competitor Comparison – Why Build on Web3 With Moralis? 

To underscore the benefits of Moralis, we compared our industry-leading Web3 APIs to two prominent competitors: Alchemy and QuickNode. In doing so, we used each provider’s Web3 APIs to fetch the data needed to build a portfolio view of Vitalik Buterin’s ERC-20 tokens. This allows us to systematically compare the number of calls and the cost of fetching the same on-chain resources with each provider’s APIs. 

Here are the results of our test:

By quickly analyzing the charts above, we can immediately determine that Moralis stands out as a clear winner. With only 18 calls at a cost of $0.000882, we were able to fetch the balance, metadata, prices, and more of Vitalik’s ERC-20 tokens when using Moralis. In comparison, the same task demanded 4,760 calls at a total cost of $0.0163091 with QuickNode. And 4,963 calls at a total price of $0.0049189 with Alchemy. 

But why are the results so different? 

The secret lies in the richness of our API responses. Since Moralis’ API responses include metadata, market data, and more, you only need one single endpoint to fetch all the information for building a portfolio view of a wallet. 

When using Alchemy or QuickNode, however, you must first use one endpoint to fetch a wallet’s token balances. From there, you then need to query each individual token for metadata, resulting in thousands of extra calls. Lastly, you also need to use a third-party provider like CoinMarketCap or CoinGecko to fetch the prices for each token. 

So, by enriching our API responses with a lot of data, we’re able to provide you with a more compelling and straightforward developer experience. To learn more about this, check out our guide comparing the industry’s leading Web3 API providers!

Moralis’ Web3 API Suite – The Best and Cheapest Way to Build Web3 Applications

Now, with an overview of Moralis, let’s dive a bit deeper into our Web3 API suite. In doing so, we’ll cover the following three APIs: 

  • Token API

With only single lines of code, you can seamlessly use the Token API to fetch and integrate token balances, transactions, metadata, and much more from any wallet. As such, when using the Token API, you can effortlessly build everything from portfolio trackers to token explorers without breaking a sweat. 

To showcase the power of the Token API, check out our token balances with prices endpoint in action:

import fetch from 'node-fetch';

const options = {
 method: 'GET',
 headers: {
   accept: 'application/json',
   'X-API-Key': 'YOUR_API_KEY'
 },
};

fetch('https://deep-index.moralis.io/api/v2.2/wallets/0xcB1C1FdE09f811B294172696404e88E658659905/tokens?chain=eth', options)
 .then(response => response.json())
 .then(response => console.log(response))
 .catch(err => console.error(err));

When calling the endpoint above, you get the token balances of the address in question along with metadata, prices, price changes over time, and much more. Check out an example of what the response looks like down below:

{
   //...
  "result": [
    {
      "token_address": "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48",
      "symbol": "USDC",
      "name": "USD Coin",
      "logo": "https://cdn.moralis.io/eth/0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48.png",

With the NFT API, you only need single lines of code to query NFT balances, metadata, on-chain price data, optimized image previews, and more. So, when working with Moralis, you can seamlessly build everything from NFT marketplaces to games with ease. 

To highlight the power of the Token API, check out the example below of how to call the getWalletNFTs() endpoint:

import Moralis from 'moralis';

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

  const response = await Moralis.EvmApi.nft.getWalletNFTs({
    "chain": "0x1",
    "address": "0xff3879b8a363aed92a6eaba8f61f1a96a9ec3c1e"
  });

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

Calling the endpoint above gives you a list of the wallet’s NFT balance. It will look something like this:

  "result": [
    {
      "amount": "1",
      "token_id": "5021",

With single API calls, you can use this premier tool to seamlessly fetch wallet balances, transactions, transfers, profile data, and more. So, when using the Wallet API, you can seamlessly build cryptocurrency wallets, portfolio trackers, and everything in between. 

To highlight the accessibility of this tool, check out the getNativeBalance() endpoint in action: 

import Moralis from 'moralis';

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

  const response = await Moralis.EvmApi.balance.getNativeBalance({
    "chain": "0x1",
    "address": "0xDC24316b9AE028F1497c275EB9192a3Ea0f67022"

  console.error(e);
}

In return for calling the getNativeBalance() endpoint, you’ll get a response displaying the native balance of the wallet in question. It should look something like this: 

{
  "balance": "44573382376487713986330"
}

Build on Web3 Tutorial: How to Query On-Chain Data with Moralis in 3 Steps 

Let’s now show you how to build on Web3 by walking you through a tutorial on how to fetch on-chain data using Moralis’ top-tier APIs. To do so, we’ll be using the getNativeBalance() endpoint as an example and demonstrate how to fetch the native balance of any wallet in three steps: 

  • Step 1: Get a Moralis API Key
  • Step 2: Write a Script Calling Moralis’ API
  • Step 3: Run the Code

However, even though we’ll be using getNativeBalance() as an example, note that you can follow the same steps to call any of Moralis’ endpoints! 

Prerequisites 

Before proceeding, you must deal with a couple of prerequisites. As such, start by installing and setting up the following: 

  • Node.js v14+
  • Npm/Yarn

Step 1: Get a Moralis API Key 

Sign up with Moralis by clicking on the button at the top right of Moralis’ homepage and follow the instructions: 

First step to build on Web3 - Sign up for free with Moralis - Showing sign up button on homepage

Next, go to the ”Settings” tab, scroll down to the ”API Keys” section, and copy your Moralis API key: 

Step 2 - Showing how to copy the Web3 API key

Please keep it for now, as you’ll need it in the next section! 

Step 2: Write a Script Calling Moralis’ API 

Start by setting up a folder in your IDE and run this command in a new terminal to initialize a new project: 

npm init

Next, keep the terminal open and install the Moralis SDK with the following command: 

npm install moralis @moralisweb3/common-evm-utils

You can then open your ”package.json” file and add ”type”: ”module” to the list: 

Opening the ”package.json” file and adding ”type”: ”module” to the code list

From here, create a new ”index.js” file and add the following code: 

import Moralis from 'moralis';

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

  const response = await Moralis.EvmApi.balance.getNativeBalance({
    "chain": "0x1",
    "address": "0xDC24316b9AE028F1497c275EB9192a3Ea0f67022"
  });

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

You then need to configure the code slightly. First, replace YOUR_API_KEY with the key you copied earlier. Next, you also have to configure the address and chain parameters to fit your query: 

Showing in the code base where to paste the API key to build and access Web3

Now that’s it; all that remains from here is running the script!

Step 3: Run the Code 

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

node index.js

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

{
  "balance": "44573382376487713986330"
}

That’s it; getting on-chain data has never been easier! From here, you can now use Moralis to build your next project on Web3 quickly, cheaply, and without breaking a sweat!
