The Smart Gateway for LLM API Calls
One unified endpoint, 20+ providers. Router One picks the optimal model by cost, latency, or quality — with automatic fallback, budget guardrails, and real-time usage tracking built in.
Unified Model API
A single POST /llm.invoke endpoint that works across OpenAI, Anthropic, Google, Mistral, and 20+ other providers. No provider-specific code, no SDK juggling — just one consistent interface with structured responses, streaming support, and automatic format normalization.
Intelligent Routing
Tell the engine what you care about — cost, latency, or quality — and it selects the best model for each request. When a provider goes down or starts degrading, traffic automatically shifts to the next best option. No manual failover, no pager alerts at 3am.
Budget & Rate Control
Set spending limits per project, per agent, or per API key. QPS throttling prevents runaway loops from burning through your quota. Real-time token counting and cost tracking mean you always know exactly what you're spending — before the bill arrives.
