What OpenRouter does
OpenRouter provides a unified API that offers access to hundreds of AI models through a single endpoint. It automatically handles fallbacks, selects the most cost-effective options, and continuously monitors the health and availability of AI providers to ensure maximum uptime. The platform supports various integration methods including a direct API, Client SDKs for type-safe model calls, and an Agent SDK for building AI agents with tool use, loops, and state management. OpenRouter normalizes the schema across different models and providers, simplifying development. It also offers features like prompt caching, reasoning tokens, and customizable provider selection based on factors like price, throughput, and latency, with options for data residency and zero data retention.
