Open Router
OpenRouter offers a unified API endpoint that enables developers to access over 300 AI models from more than 60 providers through a single interface compatible with the OpenAI SDK. It features automatic fallback mechanisms to maintain reliability by routing requests to alternative providers if one fails, and it optimizes costs by directing requests to more affordable options. The platform operates on distributed infrastructure with edge deployment, adding approximately 25 milliseconds of latency to requests. The service supports prompt caching to reduce expenses and allows data policy-based routing to control which models and providers handle specific prompts. Developers can utilize DevTools for SDK telemetry during development to capture requests, responses, token usage, and errors. OpenRouter targets developers, indie hackers, AI-native startups, teams, and enterprises seeking broad access to multiple AI models via a single API.
OpenRouter provides a single API endpoint to access 300+ AI models from 60+ providers with automatic fallback and cost-effective routing.
Multi-Model AI Application Development
Developers building AI applications can access a wide range of models from multiple providers without changing code, using a single API endpoint.
Cost Optimization in AI Usage
Applications can route requests to cost-effective providers automatically, reducing operational expenses.
Reliability Through Automatic Fallbacks
If a chosen AI provider fails, requests are automatically rerouted to alternative providers to maintain service continuity.
