How to Develop an Explorer Using KS Query APIs
Building a blockchain Explorer is now easier and more customizable than ever with KS Query APIs.
Step 1. Understand KS Query APIs
KS Query offers a powerful suite of endpoints to access:
Smart Contracts: Analyze deployed contracts and metadata
Blocks: View block details and included transactions
Transactions: Track transactions across the chain
Network: Monitor overall network activity
Note: Use the API Console on the KS Query dashboard to explore all available endpoints before you begin.
Step 2. Set Up Your Environment
Make sure you have the following tools ready:
Postman – for testing API endpoints
Browser DevTools – to inspect API traffic (useful for debugging)
Frontend Framework – React, Angular, Vue, or plain JavaScript to build your Explorer UI
Step 3. Integrate the APIs
a. Access the API Console
Go to the KS Query API Console
Navigate to All APIs Categories include:
Smart Contracts
Blocks
Transactions
Network

b. Choose Your Endpoint
Select the endpoint you need (e.g.,
/analytics/chaincode
)Click on it to open detailed documentation
Copy the endpoint URL

c. Check Required Parameters
Click on Params to view Route Details and review required inputs.

A Route Detail dialog will open with 3 tabs:
Params: Lists required header and query parameters

Blockchain & Network: Shows the blockchain context for this API (network: e.g., devnet blockchain: e.g., kalp)

API Auth Key: Displays your existing API keys
Note: Generate or copy your active API key from the API Key Generation tab

d. Test the Endpoint in Postman
Open Postman and create a new GET request.
Paste the copied endpoint into the request URL.
Add the following Headers:
Network: Enter the network name (e.g.,
devnet
).Blockchain: Enter the blockchain name (e.g.,
kalp
).API Key: Paste your API key.
Send the request and verify the response.

Step 4. Build the Frontend
After successful API testing, start building your Explorer UI. Common components include:
Tabs for: Smart Contracts, Blocks, Transactions, and Network Monitoring.
Search and Filter Options: Enable users to filter data using parameters like
smartContractName
,from
, andto
.Interactive Charts and Tables: Display blockchain data dynamically.
Step 5. Example: Display Smart Contract Data
To create a tab that displays smart contract details:
1. Use the /analytics/chaincode
endpoint.
2. Pass query parameters like smartContractName
to fetch specific results.
3. Display the results in a table format, including details like contract address, creation date, and associated transactions.
Step 6. Advanced Features
Take your Explorer further by integrating:
Real-Time Updates: Use WebSockets (when supported) for live blockchain feed
Metrics + Analytics: Integrate metrics APIs when they’re available
Custom UI Themes: Match your Explorer to your brand with a styled frontend
Step 7. Test and Deploy
Validate all endpoints return accurate data
Perform edge case testing (e.g., empty state, failed API call)
Host the frontend using platforms like Netlify, AWS, or Vercel
Step 8. Inspect Tool for Debugging
Use your browser’s Inspect → Network tab to:
Observe live API requests
Debug headers, parameters, and responses
Optimize performance
KS Query APIs empower developers to create high-performance, flexible blockchain Explorers. By combining powerful backend access with customizable UI, you can tailor your Explorer for enterprise, DeFi, or research use cases with ease.
