How a request routes

Your app sends one request to AnyRouter. AnyRouter checks the key, picks a route and, if an upstream fails, falls back to the next one. You are billed once.

FAQ

What is AnyRouter?

OpenAI-compatible gateway. 323 models, 18 providers. Free models, $4 credit on Go, $0 markup on your own keys.

How do I call models through AnyRouter?

Point your SDK at one base URL and reference models as provider/model, as in the code above. The table lists every model with its price per 1 million tokens.

Do you take a cut if I bring my own keys?

No. Route through your own provider keys and the markup is $0: what you pay upstream is exactly what you pay.

How do I get started?

Sign up in seconds, no card required. Free models cost nothing, Go adds $4 credit, and the table above shows what every other model costs.
