One API for OpenAI- and Anthropic-compatible models — multi-model gateway on Cloudflare’s edge, prepaid USD, no recurring subscription.
KeepRouter is a managed multi-model API gateway. One account and one API key reach the live catalog through the OpenAI-compatible /v1/chat/completions endpoint, the Anthropic-compatible /v1/messages endpoint used by Claude Code, and route-specific endpoints for embeddings, images, audio, and video. Routing uses an explicit public model ID, so the caller chooses the model. Billing is prepaid USD pay-as-you-go with no recurring subscription. New accounts can call the published free model before topping up. Discovery pages include llms.txt, models.md, an OpenAPI document, a quickstart, and a Claude Code guide, in English and Chinese. A compare section covers fit against OpenRouter, Portkey, LiteLLM, and other gateways. KeepRouter is not KeepBal and it is not a self-hosted LiteLLM fork.
