What is LowRouter?

LowRouter gives teams and AI agents one API key and one bill in euros for language models from many providers, European and international.

Automatic routing follows the rules each team sets: EU-sovereign providers only, the cleanest electricity grid, the lowest price, or a mix. Each response includes an estimate of its carbon emissions.

Aliases let teams switch model or provider without changing code, and a failed request falls back to another provider. LowRouter works with SDKs and coding agents that accept a custom provider.

The model catalogue is public and free to search, so anyone can compare models by sovereignty and carbon intensity before signing up.
