FAQPage Schema

How do I route API requests across multiple AI models with fallbacks?▼

OpenRouter provides unified routing across hundreds of models with automatic fallback support. Send requests to a single OpenRouter endpoint, specify multiple models in priority order, and the service automatically tries alternatives if your preferred model fails or times out.

Can I use OpenAI SDKs with multiple AI providers?▼

Yes. OpenRouter offers an OpenAI-compatible API, so you can use existing OpenAI client libraries by changing the base URL to OpenRouter and adding your OpenRouter API key. This lets you access models from Anthropic, Open AI, Meta, and others through one interface.

Does OpenRouter support streaming and structured JSON outputs?▼

OpenRouter supports both streaming responses and structured JSON outputs. You can enable streaming for real-time token delivery and use response_format to request validated JSON results, alongside configurable sampling parameters like temperature, top_p, and penalties.

What happens if my primary model isn't available?▼

Fallback routing automatically tries alternative models you've specified without requiring manual intervention. This ensures requests succeed even during provider outages or rate limits, improving reliability for production applications.

Can I use tool calling and function calls across different models?▼

Yes. OpenRouter supports function and tool calling across its model roster with a unified interface. This lets you build multi-provider applications that leverage model-specific capabilities while maintaining consistent API behavior.

How do I compare costs between different AI models?▼

OpenRouter provides pricing transparency for each model, letting you compare token costs across providers on a single dashboard. You can use this data to optimize model selection based on your budget and performance requirements.
