Access to data Ethereum transaction with blockchain.info API
As a newcomer in the Bitcoin and Blockchain technology world, you are probably eager to be ongoing with the latest transactions. However, navigation of a huge amount of data available can be irresistible. Fortunately, this article will guide you through the approach procedure for the latest data on Ethereum transaction using API -ja blockchain.info.
** What is blockchain.info API?
Blockchain.info API is an open code platform that allows development manufacturers to access and manipulate data from the blockchain network, including Ethereum. Using this API, you can download and analyze the transaction information in a structured format.
** Why use blockchain.info API?
There are serious reasons you should consider using blockchain.info api -ja:
* Real Time Updates : API provides real -time updates about the creation of a block, mining and processing transactions.
* Scalabiness : With API blockchain.info, you can handle a large amount of data without threatening performance or scalability.
* Flexibility : API supports different data formats, including JSON, which allows easy integration into your application.
Access Ethereum Date of Transaction
To access the latest data on the Ethereum transaction using blockchain.info API -ja, follow these steps:
Step 1: Register on Blockchain.info
Before you start using API, you need to register on blockchain.info. This includes the creating an account and checking the E -Stage address. After registration you will get a unique API key that will be used to authenticate your requests.
Step 2: Select API endpoints
Blockchain.info API provides heavy endpoints to download transactions data. For this example, we will use / the end point, which returns information about Ethereum Blockchain.
Step 3: Set up the NODE.JS app
To download the latest transactions using blockchain.info API, you will need to set up the noda.js application that can be associated with API and analyze the JSON answer. Here’s an example of a code clip:
`Javascript
Const Express = demand ('Express');
Const Axios = required ('axios');
Const App = Express ();
Const API_KEY = 'Your_api_Key_here';
Const blockchain_info_url = blocks/;
app.get ('/blocks/: id', Async (Req, res) => {
Const block_id = req.params.id;
Const response = awaits axios.get ($ {blockchain_info_url} $ {block_id});
Const data = answer.data;
if (data.error) {{
Return res.Status (500) .json ({Error: 'failed to retrieve data');
Iche
// Arrange the JSON response and set aside the ID -Ove transaction
Const transaction = Data.transactions;
Const transaction_ids = transaction.map ((transaction) => transaction.id);
res.Json ({transactions: transaction_ids});
});
app.listen (3000, () => {
Console.log ('API listening on Porto 3000');
});
This code sets the Express.js application that listens to on Porto 3000. Defines one end point API -ja/: ID, which accepts A Block_idparameter. The end point sends a blockchain.info API request and breaks down the JSON response, drawing the ID -s transaction. Finally, returns a list of ID -O's transaction in the JSON response.
Step 4: Start the application
To start the app, save the code clip up to the file (eg,app.js) and make it with noda.js:
Bash
Node app.js
``
This will be launched by Express.JS server on Porto 3000. You can now access the latest transaction data on Ethereum by visiting [http: // Localhost: 3000/blocks/: ID] (http: // Localhost: 3000/: ID/: ID).
Conclusion
Access to Ethereum’s latest data transaction using blockchain.info APIs is a simple process that requires minimal knowledge of blockchain technology and programming languages such as noda.js.
