Router

Router is Ramp's unified API for large language model inference. Instead of wiring separate integrations to OpenAI, Anthropic, xAI, and open-source providers, you point your code at one endpoint with one key, and Router decides which model handles each request.

The routing is cost-aware: every request is matched to the cheapest model that clears your performance threshold, so simple background tasks do not burn frontier-model tokens. Ramp says teams save around 40 percent on inference spend on average.

Because Router sits on top of Ramp's financial engine, token usage maps back to teams and budgets instead of disappearing into one shared bill. The routing layer is free through 2026, and new accounts get model credits to start.
