Zero complexity.
Replace a dozen integrations with a single API call. We handle the routing, failover, and optimization — you focus on building.
Unified API Format
Same request/response structure across all providers. Switch from GPT to Claude to Gemini with a single parameter change.
Automatic Failover
If a provider is down, we route to an equivalent model instantly. Your users never experience downtime.
Cost Optimization
Smart routing finds the best price-to-performance ratio. Use the right model for each task — not the most expensive one.
Pay As You Go
No monthly subscriptions, no commitments. Pay only for the tokens you actually consume, across any model.
Drop-in compatible.
See how simple it is to integrate Lunos into your existing stack in under a minute.
Everything you need.
Nothing you don't.
Multi-Model Access
Connect to 40+ AI models from OpenAI, Anthropic, Google, Meta, and more. Switch providers with a single parameter.
API Key Management
Generate, rotate, and scope keys with granular permissions.
Global Edge Network
Sub-100ms routing through edge nodes across 30+ regions.
Smart Routing
Automatic failover and load balancing across providers for maximum uptime.
“We switched from managing 4 separate API integrations to Lunos in an afternoon. Our AI costs dropped 35% and we haven't had a single outage since.”
“Lunos unified our entire LLM stack. We no longer worry about provider downtime. It just works automatically under the hood.”
“The ability to instantly switch between OpenAI, Anthropic, and open-source models without changing our code is an absolute game changer.”
“We tried building this middleware ourselves. Lunos does it 10x better and saves us thousands of hours in maintenance.”
“Unbelievably simple. The dashboard gives us exactly the token analytics we were missing from individual providers.”

“A massive win for our infra team. One consolidated billing account, 40+ state-of-the-art models. Highly recommended.”
“The latency is incredibly low. I was skeptical about adding an API gateway for LLMs, but I literally can't tell the difference.”
“Finally, a routing layer that makes sense. The Fallback mechanism alone has saved our production app multiple times already.”
“We integrate new models into our product on day one now. No more reading API docs every time a new provider launches a model.”
“Beautiful UI, phenomenal developer experience. Lunos is exactly what the fragmented AI ecosystem needed right now.”
