Built for production

Triple Protocol Native

OpenAI, Anthropic, and Gemini protocols — all native, zero format conversion. Use whichever SDK you prefer.

Fewer Provider Interruptions

Managed capacity and availability policies reduce interruptions from rate limits, timeouts, and temporary outages while fair-use and key-level safeguards remain in place.

Smart Routing

Automatically match each task to a suitable model. Users get one stable API while complex choices stay out of the app.

Per-Request Billing

Every request gets a generation ID. Query exact cost, tokens, and latency via the Generation API.
