# LLM Gateway

> One API for 40+ LLM providers. LLM Gateway routes OpenAI-compatible requests across providers, falls back automatically when one degrades, and records the cost of every request.

## Frequently asked questions
### What is an LLM API gateway?
An LLM API gateway sits between your application and every model provider. You call one OpenAI-compatible endpoint and the gateway handles provider credentials, request normalisation, routing, retries and failover, then returns one usage and cost record for every call.

### How many providers does LLM Gateway support?
More than 40 providers and several hundred models, including OpenAI, Anthropic, Google, Meta Llama, Mistral, DeepSeek, xAI, Groq, Cohere, Perplexity, Together and Fireworks. The catalog follows vendor releases, and any OpenAI-compatible endpoint can be added as a custom provider.

### Do I have to rewrite my application?
No. The API is OpenAI compatible, so in most stacks the only change is the base URL and the API key. Streaming, tool calls, structured outputs, vision inputs and embeddings keep working, and switching models is a single string change.

### How does failover work when a provider goes down?
Each route has an ordered provider list plus timeout, retry and circuit-breaker settings. If the primary provider errors, rate limits or times out before the first token, the request is retried on the next healthy provider with the same body, and failing providers are probed back into rotation automatically.

### Can I see and control what I spend?
Yes. Every request records provider, model, token counts, latency and cost. Spend can be broken down by key, project, team or feature, with budget alerts and hard limits that stop traffic before it exceeds the ceiling you set.

### Do I need a subscription to use the playground?
The playground on the home page is a gated preview that shows routing, fallback and cost behaviour in your browser. It needs a Google sign-in and an active plan; accounts without a plan are sent to the pricing page.
