Blockchain API Examples and Use Cases
The Mobula Blockchain API serves a variety of critical use cases in the blockchain space. Here, we will highlight three instances:
Algorithmic Trading Platforms: Algorithmic trading platforms use automated, pre-programmed trading instructions to execute orders at high speeds and volumes, which can be based on a variety of conditions including time, price, and volume. These platforms demand real-time, precise market data to make informed decisions and capitalize on market movements.
- For algorithmic trading to be effective, access to up-to-the-second market data—such as asset prices, trading volumes, and liquidity metrics—is crucial. This data enables algorithms to perform technical analysis, identify trading opportunities, and execute trades with optimal timing. Utilizing the Mobula Blockchain API provides these platforms with the detailed and timely market data they require, facilitating efficient and informed trading strategies.
Wallet Data Platforms: Wallet data platforms function as digital vaults that facilitate the storage and management of digital assets, encompassing both fungible and non-fungible tokens. Notable examples in the market include MetaMask and Rainbow.
- A key functionality of these platforms is showcasing the user's wallet activity, offering a comprehensive view of their transactions and trades. This feature is invaluable for users seeking insights into their digital asset movements. To accurately display such detailed transaction information and events, the integration of a robust Blockchain API, like the Mobula Blockchain API, is essential, providing the necessary data for a complete activity overview.
Decentralized Exchange (DEX) Analytics Platforms: DEX analytics platforms provide insights into trading activities on decentralized exchanges, offering data on trading pairs, liquidity pools, and price movements. These platforms are crucial for traders and investors looking to understand market trends, identify high-potential trading pairs, and track liquidity shifts across various decentralized exchanges.
- To deliver this in-depth analysis, these platforms must have access to real-time and historical data on trading pairs, including volume, price fluctuations, and liquidity changes. The Mobula Blockchain API can supply this critical pair data, enabling DEX analytics platforms to offer comprehensive insights and analytics. By leveraging the API, these platforms can enhance their ability to provide users with actionable intelligence on the decentralized trading landscape.

Wallet Data Platforms: Python Blockchain API Example
For Wallet Data Platforms focusing on providing users with their comprehensive wallet portfolio, utilizing the Mobula Blockchain API becomes essential. By leveraging the wallet/transactions endpoint, you can extract a detailed transaction history and portfolio composition with just the wallet address as a mandatory parameter. Here’s an updated Python example reflecting these requirements:
import requests
url = "https://api.mobula.io/api/1/wallet/transactions"
querystring = {"wallet":"0xYourWalletAddress"}
response = requests.request("GET", url, params=querystring)
print(response.text)This snippet is crafted to help Wallet Data Platforms query the Mobula Blockchain API efficiently, requiring only a wallet address to fetch a user's portfolio data, streamlining the process of displaying comprehensive wallet activities and holdings.
When you call the wallet/transactions endpoint, the response will include an array detailing all inbound and outbound transactions associated with the specified address. The response format typically provides comprehensive transaction data, including transaction hashes, amounts, dates, and other relevant details. Here's an example of what such a response might look like:

Accessing Market Data: A Tutorial on Using the Mobula Blockchain API
In this tutorial, we'll guide you through the process of retrieving market data using the Mobula Blockchain API. Leveraging this premier Web3 development tool, you can access the necessary information in three simple steps:
- Obtain a Mobula API key
- Develop a script to Use the market/data endpoint
- Execute the script
Before you proceed with querying the market/data endpoint, ensure you've covered all the prerequisites.
Prerequisites
For this tutorial on accessing market data with the Mobula Blockchain API using JavaScript, you'll need to have the following setup:
- Node.js version 16 or later
- NPM or Yarn package manager
Step 1: Obtain a Mobula API Key
To utilize the Blockchain API and the market/data endpoint, a Mobula API key is essential. To acquire this key, you must first have a Mobula account. If you haven't set up your account yet, go to the API Dashboard to begin the process.
Create an account by filling in the registration form, if you haven't already done so. Once you've done that, you can click the "Create an API key" button. You'll just have to give it the name you want, and your first key will be created!
Ensure to keep your Mobula API key handy, as you'll need it for the next steps in this tutorial.
Step 2: Creating a Script to Retrieve Market Data Using the Mobula API
For this step, initiate a new project in your preferred Integrated Development Environment (IDE). Then, open a new terminal window in your project's root directory and execute the following command to set up your environment for using the Mobula SDK:
npm install mobula-sdk
Next, establish a new file named "index.js" in your project directory and incorporate the subsequent code snippet into it:
const {Mobula} = require('mobula-sdk');
const mobula = new Mobula('MOBULA_API_KEY');
mobula
.fetchAssetMarketData({
asset: 'Bitcoin',
})
.then(response => {
console.log(response);
})
.catch(error => {
console.error('Error:', error);
});
Then, make a minor adjustment to the code by substituting MOBULA_API_KEY with the key you obtained in the previous step to initialize the Mobula API:
Next, adjust the asset constant to align with the specific market data you're aiming to query:
You're all set to execute the script now!
Step 3: Run the Script
For this last step, open a terminal, navigate to your project's root directory, and execute the command below:
node index.jsExecuting the command will run your script, and as a result, you'll receive comprehensive market data. This includes key information such as the current price, trading volume, liquidity metrics, and other relevant details for the asset you queried. Here's an example of what the output might resemble, tailored to market data:
data: {
market_cap: 1248979717233,
market_cap_diluted: 1341740018950,
