What is RouterBase?

RouterBase routes 200+ AI models from OpenAI, Anthropic, Google, Meta and more through one OpenAI-compatible API. Smart routing picks providers by price, latency or availability; automatic fallback switches in milliseconds; unified billing covers every provider in one invoice.

How to use RouterBase?

1. Create an API key — sign up and generate an sk-rb-… key from the dashboard. 2. Point your SDK at RouterBase — the OpenAI SDK works as-is; swap the base URL to https://routerbase.com/v1. 3. Call any model — pick from 200+ models across OpenAI, Anthropic, Google and more.

RouterBase Frequently Asked Questions

What is RouterBase?

RouterBase is a unified router for 200+ frontier AI models — chat from OpenAI, Anthropic, Google, Meta, Mistral, DeepSeek and xAI, plus image, video and audio from Flux, Ideogram, Veo and Kling. Smart routing, automatic fallback and unified billing are built in.

How do I start using RouterBase?

Create an account, grab your API key, and swap the OpenAI SDK base URL — you're calling any model in under 5 minutes. No SDK rewrite, no provider applications. The Playground lets you try every model in the catalog before you write a line of code.

How does RouterBase pricing work?

Pass-through token pricing plus a flat platform fee. No model-specific markups and no hidden charges. Top up your balance, watch real-time spend in the dashboard, and set per-key monthly caps so a runaway script can never bill past your ceiling.

Will RouterBase use my prompts for training?

No. Requests are forwarded to providers with zero-retention flags set wherever the upstream API supports them, and prompts are never used to fine-tune any model on our side. Disable dashboard logging entirely with one toggle if you prefer.

Does RouterBase support streaming and tool use?

Yes. Full feature parity with upstream APIs — streaming SSE, tool calling, vision inputs, JSON mode and prompt caching all behave exactly as the provider documents. New upstream features land in the unified API within days, not quarters.

Can I use my own provider keys with RouterBase?

Yes. BYOK is supported for OpenAI, Anthropic and Google. The platform fee is flat, token costs pass through to your own provider account, and you keep your committed-spend discounts. Traffic falls back to the pooled provider when you hit a soft cap.
