Who benefits from an OpenRouter alternative?

Developers and companies that want to run a multi-model API under compliance requirements: GDPR-compliant, hosted in the EU, with central control and personal support instead of pure self-service.

Is the innoGPT API OpenAI-compatible?

Yes. The innoGPT API is an OpenAI-compatible REST API. Existing code, standard libraries and automation tools like n8n, Make or Zapier can talk to it directly.

Which models can I use via the API?

Over 50 AI models, including GPT, Claude, Gemini, Mistral and LLaMA. You pick the model per request parameter – through the same endpoint.

How does data protection work?

innoGPT is GDPR-compliant and hosted in the EU. Data is not used to train external models. You can find details on the data protection & security page.

Can I combine the API with the app?

Yes. The API is part of the innoGPT platform: your team works in the ready-to-use interface while your systems and automations use the same models via the API.

How do I get started with the API?

You create an account and generate your API key. The easiest way to start is a demo appointment.
