Ramp Router

What Ramp Router is

Ramp Router provides one API endpoint for sending requests to AI models from OpenAI, Anthropic, other providers, and selected open-source sources. It chooses routes using quality, cost, and availability. Eligible requests may move to a lower-cost tier when Router expects no quality change, or to another available model when a provider is unavailable or rate-limits a request. OpenAI- and Anthropic-compatible APIs allow switching by changing the base URL. The Responses endpoint supports cross-provider models, fallback routing, spend tracking, and request inspection. Authentication records usage, model, provider, and cost, while usage analytics, budget controls, and virtual API keys are available. The homepage describes privacy controls and zero data retention on eligible models; vetted providers offer United States-hosted models with zero-retention options. Router serves individual developers and teams in the United States. The Free routing plan is free through 2026, includes $26 in initial credits, and charges list token prices.
