MuiRouterClaude API Gateway
Use Claude via one API
Point Claude Code, the Anthropic SDK or any OpenAI-compatible client at MuiRouter and call Claude with a single key. No separate Anthropic account, prompt caching passes through, and the same key also reaches GPT, Gemini and Grok.
Everything you need to call Claude
Native Anthropic endpoint
MuiRouter exposes a native /v1/messages endpoint, so Claude Code, the Anthropic SDK and any Anthropic-native client work by only changing the Base URL and key.
No Anthropic account required
Calls run on your MuiRouter balance — sign up, generate a key, and skip setting up a separate Anthropic account.
Prompt caching passes through
Repeated system prompts and long context that hit the cache are billed at the lower cached-input rate automatically.
Also reachable OpenAI-compatible
Prefer the OpenAI request shape? Call the same Claude models through MuiRouter's OpenAI-compatible endpoint instead.
