The cheapest Claude API

UberLLM serves Claude models (Opus, Sonnet, Haiku) through the cheapest healthy seller, callable with either the OpenAI SDK or the Anthropic SDK (/v1/messages). UberLLM gives you one OpenAI-compatible API key and base URL for every major model, routing every request to the cheapest healthy seller for that model and billing the price shown, with UberLLM's 10% fee already included.

base_url = "https://api.uberllm.dev/v1"

FAQ

Can I use the Anthropic SDK with UberLLM?

Yes — point the Anthropic SDK at the UberLLM /v1/messages endpoint with your key. Claude models work unchanged.
