Tutorial: Getting Started with Claude Code via YEScale API

This guide will walk you through setting up and using Claude Code, a powerful AI coding assistant from Anthropic, through the YEScale API. Claude Code operates directly in your terminal to help you build, debug, and understand code more efficiently.

✨ Key Features of Claude Code

Comprehensive Codebase Analysis: Claude Code can understand the entire structure of your project, not just isolated snippets. This allows it to perform complex and consistent modifications across multiple files.

Deep Terminal Integration: It works within your command-line interface, interacting directly with familiar tools like Git, GitHub, and CI/CD systems to execute commands.

Automated Development Workflow: It can independently handle a complete task from start to finish—from reading an issue and writing the code to running tests and creating a Pull Request.

Accelerated Onboarding and Refactoring: It helps new developers get up to speed on a project quickly and assists in refactoring large-scale codebases safely and effectively.

📋 Prerequisites

Before you begin, ensure you have Node.js (version 18 or newer) installed on your system.

🚀 Setup and Configuration

Follow these steps to install and configure Claude Code to work with YEScale.

Step 1: Install the Claude Code CLI

First, install the Claude Code command-line tool globally using npm. Open your terminal and run the following command:

Step 2: Create a YEScale API Key

Navigate to the YEScale platform and generate a new API Key. Make sure to assign it to the claude-code group. YEScale is an enterprise-grade platform that provides access to various AI models.

Step 3: Set Environment Variables

Next, you need to configure your terminal environment to point Claude Code to the YEScale API endpoint and use your unique API key. This is a common practice for integrating with third-party API providers.

Run the following commands, replacing sk-xxxxxxx with the actual API key you obtained from YEScale:

Step 4: Choose Your Model

YEScale provides access to Anthropic's powerful Claude 4 models:

claude-opus-4-20250514: Anthropic's most advanced and powerful model, ideal for complex reasoning and coding tasks.

claude-sonnet-4-20250514: A model that balances high performance with speed, perfect for everyday development and rapid response needs.

You can specify which model to use when you run the tool. For example, to use Opus 4, you would start Claude with the --model flag.

Step 5: Launch Claude Code

With the configuration complete, you are now ready to start using Claude Code. Navigate to your project's directory and run the claude command:

You can now interact with Claude in your terminal to ask questions about your codebase, debug issues, or build new features.
