Start for free.
No card needed.
50 requests a day, one URL, automatic failover — before you spend a cent.
Call anyrouter/free from any OpenAI-compatible client. AnyRouter routes the request to the best available free model and falls back automatically if that model is unavailable. No BYOK setup, no credit balance required.
What you get
No credit card required
Sign up, create an API key, and start routing requests immediately. No billing info needed to get started.
One OpenAI-compatible URL
A single base URL and anyrouter/free as your model id — no per-provider SDKs, no client rewrites, no key rotation.
Access to free models
Each request is routed to the best free model available at that moment, spanning multiple providers.
Automatic failover
If the primary free model is unavailable or rate-limited, AnyRouter falls back to the next candidate automatically.
