Model gateway, live
SwitchBoard
One endpoint for every model your business relies on.
SwitchBoard is an OpenAI-compatible gateway that places Claude, Gemini and GPT models behind a single address. It applies routing policy, fails over automatically when a provider is rate-limited or unavailable, and attributes every token to the application that used it.
Why it matters.
Teams that integrate providers directly end up maintaining several SDKs, several sets of keys and their own retry logic, and still lose availability when one provider has a bad hour. SwitchBoard moves that concern into the platform, so applications stay simple and resilient.
Provider-neutral API
One OpenAI-compatible interface for Claude, Gemini and GPT. Change models through configuration, not code.
Automatic failover
Rate limits, timeouts and outages trigger an ordered fallback chain, transparently to the caller.
Scoped service keys
Each application receives its own key, with its own model allow-list and spending limits.
Usage and cost attribution
Token usage and cost per application and per model, available in the dashboard and through the API.
