RouterBase

About RouterBase

RouterBase is a unified API that routes requests to more than 200 AI models from providers including OpenAI, Anthropic, Google DeepMind, Meta, Mistral, DeepSeek, Qwen, xAI, Cohere, Stability AI, Runway, Suno, ElevenLabs, and Black Forest Labs. It is compatible with the OpenAI SDK, so existing integrations can switch providers by changing the base URL rather than rewriting code. Official SDKs are also available for Python, Node.js, Go, and Ruby, and the service integrates with tools such as LangChain, LlamaIndex, the Vercel AI SDK, Cursor, and Continue through their OpenAI provider configuration.

The service includes smart routing that selects a provider per request based on price, latency, or availability, and automatic fallback to another provider if the primary one fails. It provides unified billing across providers on a single invoice, with pass-through token pricing plus a flat platform fee, real-time spend tracking, and per-key monthly spend caps and rate limits. Usage analytics can be tracked by model, key, or project and exported to CSV or queried via API. Bring-your-own-key (BYOK) support is available for OpenAI, Anthropic, and Google, allowing token costs to pass through to a user's own provider account while retaining any committed-spend discounts.

RouterBase states that requests are forwarded to providers with zero-retention flags set where supported upstream, that prompts are not used for model fine-tuning on its side, and that dashboard logging can be disabled. Data processing is available in EU, US, and APAC regions, with region pinning and per-key region locks offered on Enterprise plans, along with a signed DPA on request. It supports streaming, tool calling, vision inputs, JSON mode, and prompt caching. The product is aimed at development teams building applications across multiple AI model providers who want to consolidate access, billing, and failover behind a single API.
