About

LowRouter is a European AI gateway for agents and apps, providing one API key and one bill in euros for language models from European and international providers. Set routing rules per API key, including EU-sovereign providers only, lower-carbon routing, lower-cost routing, or a combination. Responses report the provider and region, with an estimated carbon figure when model data supports it. Coding agents such as OpenCode, Claude Code, and Cline can use LowRouter as a custom provider. Apps built with LangChain or the OpenAI SDK can also connect. Aliases let you switch models or providers without changing code, and automatic routing can send eligible requests to another provider when a route fails. The public model catalogue can be searched by sovereignty and carbon intensity. Tokens are billed at provider prices without a per-token markup; credit top-ups carry a fee, and there is no subscription. LowRouter is operated by Carbonifer SAS in Nantes, France.

About

Zerouter is an OpenRouter-style API gateway for coding agents. Point Claude Code, Codex CLI or Cursor at the Zerouter API, keep your prompts and tools unchanged, and call Claude, GPT, Gemini, Grok and Kimi with one key. Requests go to official model APIs with no silent model swaps; usage is billed per token with published rates (frontier models up to ~93% below list). Pay-as-you-go, no subscription.
