API endpoints are essential for integrating and automating various processes in blockchain development. KALP Studio's API Gateway offers a streamlined solution to build and manage API endpoints, simplifying integrating and scaling APIs. This guide will walk you through the key features and the steps to effectively use KALP Studio's API Gateway, making it easier to manage your APIs efficiently and easily.

Prerequisites

Before exploring the API Gateway, ensure you have the following things set up.

• Kalp Studio Account: Create your account on Kalp Studio here.
• Custodial Wallet: Before proceeding further, you would need to have Kalp Studio’s Custodial Wallet connected, for this tutorial, we are connecting our wallet to the Ethereum Blockchain and Holesky Network. If you haven’t connected your wallet yet, please go through our first tutorial of this series here: Creating your Custodial Ethereum Wallet on Holesky Network, using Kalp Studio.
• Deployed Solidity Smart Contract: To generate API Endpoints, we must first deploy our desired smart contract on Kalp Studio using the Kalp Instant Deployer. To ensure you deploy your smart contract on Kalp Studio, look at the second tutorial of this series: Create Your First Smart Contract in Solidity and Upload it to Kalp Instant Deployer.

Now that everything is set up, let’s understand the KALP API Gateway.

What is KALP Studio's API Gateway?

KALP Studio's API Gateway is a robust platform for managing API traffic and enabling seamless service integration. It allows you to create, monitor, and manage API endpoints with minimal effort, making it an ideal solution for developers and businesses aiming to optimise their backend operations. Key benefits include:

• Simplified API Management: Easily create, update, and delete API endpoints through a user-friendly interface.
• Scalability: KALP Studio’s infrastructure ensures your APIs can handle increasing traffic without a hitch.
• Security: Implement authentication and rate limiting to protect endpoints from unauthorised access and abuse.
• Analytics & Monitoring: Gain insights into API performance with detailed logs and analytics.

Accessing the API Gateway

• On your KALP Studio Console’s dashboard, scroll down and click on the API Gateway card.

• Once you click on the button, you’ll be redirected to the API Gateway dashboard, where all your smart contracts deployed using the KALP Instant Deployer are listed, with relevant details like Smart Contract ID, Category, Status, Network, the Blockchain it’s been deployed on, etc.

• For the smart contract whose endpoints you want to generate, scroll towards the right and see the section “Action”. Under this column, click on Generate Endpoints.

• Once you click on Generate Endpoints, you’ll get the alert stating that you have successfully generated the endpoints and the button will change to “Re-Generate Endpoints”.

• To check the endpoints, click on the ID of your desired smart contract.

• Here, you can now see that the endpoints are now accessible. With other details, like the Method, Function Name, Route etc. You can also find the Smart Contract Address mentioned above as well.

• To explore the Route Details, click the Check Params button. After clicking on it, you’ll see a pop-up where you can check the Params and the API Auth Key.

Conclusion

KALP Studio's API Gateway is a powerful tool that simplifies managing and scaling your APIs.
