Melious is an AI gateway from Saarbrücken, Germany, that gives access to more than 60 open-weight models through one API compatible with the OpenAI and Anthropic SDKs. Requests are distributed across inference providers in eight European countries, and the gateway tries the next provider automatically if one fails. Users choose a routing flavor such as balanced, speed, price, eco or batch by adding a suffix to the model name. Besides text models, the service offers embeddings, image generation, speech models and a chat interface with tools like web search and code execution. Melious does not route to providers outside Europe, so there is no setting to enable for European-only routing.

EUrouter is an AI gateway from Amsterdam, Netherlands, that offers one OpenAI-compatible API for more than 100 language and other AI models. Requests are routed by price, latency and availability, with failover between providers, per-key spend limits and usage monitoring. Its providers include Mistral AI, OVHcloud, Scaleway, IONOS and other European companies, as well as European regions of AWS Bedrock and Microsoft Foundry. Routing options let users allow or exclude individual providers, cap data retention at zero days and use the eu_owned option to limit requests to providers headquartered in the EEA. Developers who already use OpenRouter-style integrations can switch by changing the base URL.
