One base URL and key work with virtually any app, SDK or self-hosted chat client that supports a custom API address.
Route requests to OpenAI models, Claude, Stability diffusion, Azure TTS and vector database services from a single account.
Consumption is metered in points with a published multiplier, so you pay for what you use rather than a flat subscription.
Identical request bodies return cached answers for free for 24 hours, and a header can disable caching when freshness matters.
One OpenAI-compatible API to route, monitor and control 250+ LLM models
Keep your existing OpenAI SDK code and change only the base URL to reach 250+ models from 40+ providers through one integration.
If a provider errors, times out or rate-limits, the gateway can retry up to twice on another provider within the same request, so your app still gets a response.
Track requests, tokens, total spend and average cost per 1K tokens, plus per-model and per-provider breakdowns, cache hit rates and error monitoring.
Detect prompt injection, jailbreak attempts, PII, card numbers and secrets, then block, redact or warn; manage all provider keys in one scoped dashboard.
Offers broader multi-provider model routing with instant top-ups, but lacks self-hosted deployment flexibility.
