Question 1

What is KeepRouter?

Accepted Answer

KeepRouter is a multi-model large-language-model (LLM) API gateway compatible with both the OpenAI and Anthropic (Claude) API formats. It lets you call Claude, GPT, Gemini, Qwen, Kimi, Zhipu GLM, DeepSeek and more through a single API key.

Question 2

Which models does KeepRouter support?

Accepted Answer

Claude (Anthropic), GPT (OpenAI), Gemini (Google), and Chinese models including Qwen, Kimi, Zhipu GLM, DeepSeek and MiniMax — all through one unified gateway and one key.

Question 3

Is KeepRouter compatible with the OpenAI and Anthropic APIs?

Accepted Answer

Yes. KeepRouter speaks both wire formats: use the OpenAI /v1/chat/completions endpoint, or the Anthropic /v1/messages endpoint (the same one Claude Code and the Anthropic SDK use), with the same key and the same models.

Question 4

How is KeepRouter billed?

Accepted Answer

Pay-as-you-go with prepaid credits in USD — you pay only for the tokens you use, with no monthly fee. New accounts get free trial credit, and you can top up by credit or debit card (processed by Paddle as Merchant of Record).

Question 5

How do I get started with KeepRouter?

Accepted Answer

Sign up with your email, create an API key, point your base_url at KeepRouter, and call it from any OpenAI-compatible client or directly with Claude Code / the Anthropic SDK.
