About

RouteMux is a reliability-first AI gateway. One API key reaches models from OpenAI, Anthropic, Google, xAI, DeepSeek, Qwen and more through the SDK you already use. Requests fail over across redundant routes, and you only pay for the ones that succeed. Pay-as-you-go pricing starting at $10. It is built for developers and teams shipping AI features who want a single integration point, clear usage tracking and dependable routing across providers.

Key Features

One API key for models from many providers
Automatic failover across redundant routes
Pay only for requests that succeed

Use Cases

Keeping a production AI feature online by failing over across model providers when one has an outage
Comparing and swapping models such as GPT, Claude and Gemini without rewriting integration code
Adding image or video generation to an app through the same API and billing account

FAQ

What is an AI gateway (AI router)?

An AI gateway is a unified access layer between your application and model providers. RouteMux puts hundreds of AI models behind one API and one key, handling routing, billing, and failover on the backend so you don't integrate each provider separately.

How is RouteMux different from OpenRouter, and is it an alternative?

RouteMux is an alternative to aggregator gateways like OpenRouter, built reliability-first: multi-layer redundancy for high availability, transparent usage-based billing, and a refundable balance.

How do I use RouteMux with cc switch, Claude Code, or Cursor?

Point the tool's base_url at RouteMux's gateway and use your RouteMux key. OpenAI, Anthropic, and Vertex protocols are supported, so existing setups switch over by changing one line.

Which models and protocols are supported?

Hundreds of models across OpenAI, Anthropic, Google, DeepSeek, MiniMax, ByteDance and more, compatible with the OpenAI, Anthropic, and Vertex protocols. New models are added continuously.

How does billing work, and can I get a refund?

Usage-based, prepaid credits with one unified bill and transparent markup, no monthly minimum. Any unused account balance can be refunded at any time.

Am I charged for failed calls, and what are the rate limits?

Only successful requests are billed — failures and timeouts cost nothing. Rate limits are configured per account and the current RPM/TPM and concurrency ceilings are visible in the console, not hidden.
