How to Use Openrouter
Get started in a few simple steps
Get Your API Key
Sign up at openrouter.ai and generate your API key. The API is OpenAI-compatible so you can often drop it in as a replacement in existing code with minimal changes.
Choose Your Models
Browse the model catalog and select the models you want to use. Configure fallback chains so your application stays available even when a specific model has issues.
Monitor and Optimize
Use the dashboard to track usage and costs across all models. Identify which models perform best for your specific use cases and optimize your routing accordingly.
OpenRouter's Core Features in Detail
Powerful features from OpenRouter
Single Integration for Everything
Integrating with every AI provider separately creates maintenance overhead and vendor lock-in. OpenRouter handles all those relationships so a single integration gives access to the entire AI model ecosystem
Automatic Reliability
Production applications need fallbacks when models go down or hit rate limits. OpenRouter's automatic failover keeps applications running without manual intervention
Cost Visibility
Having all AI spending in one dashboard makes it much easier to understand and optimize costs across a multi-model application architecture
OpenAI Compatibility
The OpenAI-compatible API format means existing code can often switch to OpenRouter with minimal changes - just swap the endpoint and get access to far more models
