Ramp Router

What Ramp Router is

Ramp Router provides one API endpoint for requests to AI models from OpenAI, Anthropic, and other providers, including select open-source models. It routes eligible requests according to quality, cost, and availability: it may choose a lower-cost tier when it expects quality to hold, or another available model if a provider is unavailable or rate-limits a request. Its OpenAI- and Anthropic-compatible APIs allow switching by changing the base URL. The Responses endpoint supports cross-provider requests, fallback routing, spend tracking, and request inspection. Authentication helps track usage, model, provider, and cost; usage analytics, budget controls, and virtual API keys are also listed. The homepage describes built-in privacy controls and zero data retention on eligible models. Vetted providers offer models hosted in the United States, with zero data retention options. Router serves individual developers and teams in the United States, with more countries planned; enterprise features are described as coming soon. Free routing is offered through 2026, with a list price for tokens used and the first $26 in credits included. Users do not need a Ramp card, company account, or LLC.
