Windsurf Integration

Windsurf (formerly Codeium) is an AI-powered coding assistant that integrates into popular IDEs including VS Code, JetBrains, Vim, and others. It provides intelligent autocomplete, AI chat, and code editing features powered by advanced language models.

Windsurf supports custom model endpoints for enterprise deployments, allowing you to connect LLM API as your AI backend.

Prerequisites

An LLM API account with an API key
Windsurf installed or accessible

Setup

Get Your LLM API Key

Log in to your LLM API dashboard
Click Create Key to Start
Copy your new API key immediately — it will only be shown once
Store the key securely (e.g., in a password manager or .env file)

LLM API is an OpenAI-compatible gateway that gives you access to dozens of AI models through a single API key and endpoint.

Configure LLM API in Windsurf

Open your IDE with the Windsurf extension installed.
Open Windsurf Settings (click the Windsurf icon, then Settings).
Navigate to the "Model" or "Enterprise" configuration section.
Configure the custom endpoint:
- API Key: paste the key you copied from app.llmapi.ai/api-keys
- API Endpoint: https://api.llmapi.ai/v1
Click "Save" to apply the settings.
Restart your IDE --- Windsurf will now use LLM API for all AI features.

Test the Integration

Verify that Windsurf can successfully communicate with LLM API by sending a test request. All requests will now be routed through LLM API.

For Jupyter Notebook users, set the Windsurf Authentication Token in settings after installing the codeium-jupyter package.

Benefits of Using LLM API with Windsurf

Multi-Provider Access: Use models from OpenAI, Anthropic, Google, and more through a single API
Cost Control: Track and limit your AI spending with detailed usage analytics
Unified Billing: One account for all providers instead of managing multiple API keys
Caching: Reduce costs with response caching for repeated requests
