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

Spendline is a hosted AI gateway and cost-management tool for software companies that offer AI features in their products. It routes model requests through a gateway and records usage and cost by customer and agent, helping engineering and finance teams compare AI spend with customer revenue. Teams can set nested budgets for companies, teams, agents, and customers; configure alerts and approval workflows; and apply rules to route requests to lower-cost models. Spendline also provides usage reporting and month-end checks that compare recorded usage with provider invoices. The service supports multiple model providers and offers controls for managing AI usage across customer-facing applications.
