What is OpenRouter?
OpenRouter is a unified API for AI models: 500+ models from 80+ providers, including Anthropic, OpenAI, Google, Meta, Mistral, and Microsoft, all behind one OpenAI-compatible interface. Because routing is distributed, a failing provider falls back to another automatically, and edge infrastructure keeps latency low. Billing is credit-based rather than per-provider subscriptions, so the same balance works across every model, and custom data policies let you control which models and providers ever see your prompts.
It also surfaces live pricing and throughput per provider, so you can compare the real cost of the same model across hosts. The platform reports 200T+ monthly tokens, 10M+ users, and 250k+ apps built on it, including Replit, Hermes Agent, and Kilo Code.

FAQs
Common questions about OpenRouter
How does OpenRouter pricing work?
You buy credits that work across any model or provider, instead of holding a subscription with each vendor. Per-token prices vary by model and are shown alongside each one.
Do I need to change my code to use it?
The API is OpenAI-compatible, so most integrations work by changing the base URL and key. Switching models is then a string change rather than a rewrite.
What happens if a provider goes down?
Requests fall back to another provider serving the same model automatically, which is the main reason teams route through OpenRouter rather than calling vendors directly.
