About

RouteMux is a reliability-first AI gateway. One API key and one endpoint reach models from OpenAI (GPT), Anthropic (Claude), Google (Gemini), xAI (Grok), Meta (Muse Spark), DeepSeek, Alibaba (Qwen), Moonshot (Kimi), Zhipu (GLM) and MiniMax, so developers and small engineering teams can use several providers without maintaining multiple integrations. It supports OpenAI Chat Completions and Responses, Anthropic Messages, and Google Vertex. Requests run over redundant upstream routes; failed requests and timeouts are not charged. The prepaid USD wallet uses pay-as-you-go billing and starts at $10, with no subscription, seat fees or monthly minimum.

Features

Protocol-compatible API
Supports OpenAI Chat Completions and Responses, Anthropic Messages, and Google Vertex; keep the SDK and change the base URL.
Redundant upstream routes
Requests run over redundant upstream routes, reducing the chance that one provider's bad hour interrupts requests.
Success-only billing
Failed requests and timeouts are not charged.
One console and shared balance
Manage API keys, per-key quotas, usage and request logs in one console; text, image, video and speech use the same key and balance.
