**Web3 wallet trackers provide comprehensive wallet analysis and tracking tools for cryptocurrency asset investors by integrating blockchain data APIs. Users can use wallet trackers to track the total assets and transaction history of specific wallet addresses, analyze historical transactions to discover trading trends, set asset price alerts, generate wallet reports, and mark important wallet addresses. Wallet trackers support cross-chain asset tracking and have wide data coverage. They have become an essential tool in the cryptocurrency market.**

When developing a Web3 wallet tracker, various types of data need to be processed, and there may be challenges in integrating and processing this data, including but not limited to the following basic data:

1/ Blockchain transaction data: It is necessary to obtain and parse transaction data on the blockchain. This may involve handling transaction formats from different blockchain networks and addressing issues such as transaction confirmations and confirmations.

2/ Blockchain state data: In addition to transaction data, it may be necessary to obtain other state data on the blockchain, such as the state of smart contracts or the current state of on-chain assets.

3/ User wallet data: It is necessary to obtain the asset balance and transaction history of user wallet addresses. This involves interacting with users’ wallets and ensuring the security and privacy protection of the data.

4/ Real-time price data: To display the real-time value of assets, it is necessary to obtain price data for cryptocurrencies. This may involve integrating with multiple exchanges or price data providers and handling price data from different sources.

5/ Data security: As sensitive user data, such as private keys or transaction history, is involved, it is necessary to ensure the data security of the tracker, such as encrypted data transmission and secure storage.

NFTs are a special form of cryptocurrency asset with uniqueness and non-fungibility on the blockchain. They have wide applications in digital art, gaming, and collectibles, and the rapid growth of the NFT market has been a significant trend in the digital asset field in recent years.

**Building NFT API Requests**
To start using the NFTScan API, developers need to write API request code based on the chosen programming language and use the request parameters and response data format provided in the NFTScan API documentation to construct the requests.

Here are the steps to build an NFT API request:

1/ Select a programming language: Developers need to choose a programming language they are familiar with or prefer to write the API request code. Common choices include Python, JavaScript, Java, etc. Make sure the selected programming language supports HTTP requests.

2/ Import the required HTTP library: Depending on the chosen programming language, developers need to import the corresponding HTTP library to send HTTP requests and handle responses. For example, in Python, you can use the requests library, and in JavaScript, you can use the Axios library.

3/ Build the API request: Based on the information provided in the NFTScan API documentation, developers need to construct the API request. This includes the following aspects:

- Choose the API interface: Select the desired API interface from the API documentation, which refers to specific functionality or data to be accessed.
- Determine the request method: Decide which HTTP request method to use, such as GET, POST, etc.
- Set request parameters: Set the required parameters for the request based on the instructions in the API documentation. This may include query parameters, request body data, etc.
- Configure request headers: Set the headers of the HTTP request as needed, such as authorization information, content type, etc.
- Send the request: Use the imported HTTP library to send the constructed request and retrieve the response data.
- Handle the response: Parse the response data according to the API’s response format (usually JSON or XML), extract the desired information, and further process or display it as required by the application.

4/ Process API response: Once the API response is received, developers need to handle the response data. This includes parsing JSON or XML data, extracting the required information, and further processing or displaying it according to the application’s needs.

For example, to retrieve Account Overview Statistics “/v2/statistics/overview/{account_address}” for the address 0xca1257ade6f4fa6c6834fdc42e030be6c0f5a813 using an HTTP GET request to the API endpoint, you can use the Python requests library to build the request code.

`import requests

# Set API endpoint and account address
api_endpoint = "https://api.nftscan.com/v2/statistics/overview/"
account_address = "0xca1257ade6f4fa6c6834fdc42e030be6c0f5a813"

# Build the complete API request URL
url = api_endpoint + account_address

# Send HTTP GET request
response = requests.get(url)

# Check if the request was successful
if response.status_code == 200:
    # If successful, parse the response data
    data = response.json()
    # Handle the response data, further processing or display can be done here
    print(data)
else:
    # If the request failed, print the error message
    print("Request failed, status code:", response.status_code)`

Developers can access NFT data according to their construction needs. NFTScan NFT API provides developers with powerful NFT data resources for building various NFT-related applications and solutions. Whether it is developing a simple NFT trading marketplace or a complex NFT ecosystem, NFTScan NFT API can provide developers with comprehensive NFT data required for their projects.
