Ethereum Simple Address Verify via API -JA
As an Ethereum developer, you are probably familiar with the important monitoring of the blockchain transactions. One way to achieve this is the use of APIs that allow you to ask the Ethereum network and retrieve data on specific addresses. In this article, we will explore how to use the Etherscan API (previously known as Blockscout) to perform an easy address check.
What is the Etherscan API?
Etherscan is a blockchain explorer of an open code that provides access to various data on Ethereum nodes, transactions and property. It was built on top of the blockchain.info platform and offers a comprehensive APA API apartment to access and ask the Ethereum network.
Why use Etherscan API?
Using the Etherscan API offers several advantages:
* Real Time Data : API provides updated transactions, blocks and other blockchain events.
* Scalability : API is designed to handle high quantities of requests, which makes it suitable for large applications.
* Flexibility : APIs can be used in different programming languages, including node.js, Python and Javascript.
Easy address checks via Etherscan API -JA
To see if a particular Ethereum address has made any transactions, you will need:
- Register an account on Etherscan or blockchain.info
- Get your API keys (if necessary)
- Choose the final point of API for your own case desired use
Here’s an example of a Python code clip showing how to make an easy address check using the Etherscan API -ja:
`Python
Importing the request
Def Get_transactions (Address):
URL = F ” & Action = GettransationCount & Address = Address} & Apikey = YouR_Pi_KEY”
Answer = Requirements.GET (URL)
If the answer.status_code == 200:
Return int (Response.json () [“result”])
else:
Return none
Replace your_api_Key with the actual Etherscan API
API_KEY = “Your_api_KEY”
Address = “0x1234567890ABCDEF”
Replace with the address you want to check
Transaction_count = get_transactions (address)
Print (F “{{Address} has {transaction_count} transactions.”)
`
In this example, we use the libraryrequest ‘to send the ETERSCAN API requests with the specified parameters. Then we break up the answer to JSON to take over the number of transactions.
handling and safety of errors
When submitting a request for external API -it is crucial to solve errors and ensure safety. U gornjem primjeru dodali smo osnovno rukovanje pogreškama koristeći resformus.status_code i` povratna vrijednost.
In addition, remember to replace your actual API key with valid to avoid unauthorized approach.
Conclusion
Ethereum provides an excellent solution for monitoring the blockchain transactions. By using the ETherscan API, you can effectively perform easy address checks and be ongoing with the latest information on Ethereum nodes and transactions. With this article as a starting point, you will be well on the way to the construction of robust applications that communicate with the Ethereum network.
