How does a free LLM API router work?
Register for a workspace, add an HTTPS provider endpoint and your own API key, then create a unified key. Existing OpenAI clients can use this server’s /v1 endpoint. Use model auto for fallback across your configured models, or specify an exact model ID to keep the model fixed.
Understand free AI API limits
Upstream providers control free quotas and eligibility. Local request caps do not account for every token or credit limit. Check current provider terms and disable paid overages before connecting.
