FAQPage Schema

How do I route requests across multiple LLM providers like OpenAI and Claude?▼

Intelligent model routing enables multi-model workflows across providers like OpenAI and Claude. You can dynamically select models and configure fallbacks through a single API endpoint to ensure continuous operation if one provider fails.

What's the best way to optimize API costs when using multiple language models?▼

Cost optimization is achieved through per-model pricing tracking and dynamic model selection. By routing requests based on task complexity, you can maintain budgets while leveraging real-time analytics to monitor spending across 200+ models.

How do I integrate streaming responses and function calling into my AI application?▼

Streaming responses and function calling are supported as optional features when posting chat completion requests. You can enable real-time streaming by configuring the API endpoint to progressively return generated text.

Can I use a single API key to access models from different providers like Gemini and Llama?▼

A single API key from openrouter.ai grants unified access to 200+ language models across providers including Gemini and Llama. This single endpoint eliminates the need to manage multiple provider-specific API keys.

How do I set up API integration for multi-model chat completions?▼

Setup requires creating an account at openrouter.ai, obtaining an API key, and posting chat completion requests to the /api/v1/chat/completions endpoint with a specified model parameter.

Does a unified AI API gateway support vendor lock-in reduction for multi-model apps?▼

A unified API gateway reduces vendor lock-in by abstracting provider-specific implementations behind a single interface. This allows multi-model apps to dynamically switch between providers without altering core application logic.
