Sider Integration

Sider is an AI-powered browser extension and sidebar that brings ChatGPT, Claude, Gemini, and other AI models to every webpage you visit. It offers features like page summarization, writing assistance, translation, and custom AI actions --- all accessible from a convenient sidebar.

Sider supports bring-your-own-key configurations, allowing you to connect LLM API for model access.

Prerequisites

An LLM API account with an API key
Sider 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 Sider

Open Sider by clicking its icon in your browser toolbar.
Navigate to Settings → API Keys or Advanced Settings.
Select "OpenAI" or "Custom Provider" as the API type.
Enter the following details:
- API Key: paste the key you copied from app.llmapi.ai/api-keys
- Base URL: https://api.llmapi.ai/v1
Select the model you wish to use.
Click "Save" --- Sider will now use LLM API for AI features.

Test the Integration

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

With LLM API, Sider can access multiple AI models through a single key, giving you flexibility across all web-based AI tasks.

Benefits of Using LLM API with Sider

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
