Reliable Routing, Your Keys, Full Control.
TheRouter adds health-aware routing, automatic failover, billing visibility, and governance on top of your provider accounts.
Keep your existing provider relationships and pricing. TheRouter becomes the AI infrastructure layer for routing, policy control, and team visibility.
Why TheRouter
Not just an API proxy — a control plane that makes your AI stack more reliable, transparent, and flexible.
Zero Lock-in
Keep your provider accounts and pricing. Switch models or providers by changing one string — no migration, no rewrite.
- OpenAI SDK compatible — works with Cursor, Claude Code, any client
- Bring your own API keys, keep your existing contracts
- Add or drop a provider in seconds, not sprints
Smart Routing
Automatic failover, provider health tracking, and approved cost-aware routing keep requests moving without hiding what the router did.
- Automatic failover when a provider goes down
- Approved model-basket optimization (Beta)
- Measured routing evidence in request logs and analytics
Full Visibility
See exactly where every token goes. Track usage by team, key, or model — and set limits before you get a surprise bill.
- Real-time token & cost tracking per API key
- Spending limits and budget alerts
- Full audit trail for every request
Power OpenClaw Agents Across Every Channel
Build reliable multi-channel AI bots with automatic failover, multimodal support (vision, audio, PDF), and 125+ models. TheRouter adds health-aware routing, cost visibility, and enterprise security to your OpenClaw deployments.
Cut AI Spend With Guardrails
TheRouter helps you compare baseline cost vs selected route, shadow-test cheaper approved models, and prove savings in logs and analytics.
Approved Model Basket
Pick a baseline model, then approve cheaper alternatives for the same workload. Start in shadow mode, then opt into live cost routing only for that basket.
Prompt Caching
Long repeated instructions can bill at cached rates when the upstream route supports it. This is especially useful for agents and workflows with heavy system prompts.
Measured Savings Evidence
Request logs and Activity show baseline charge, selected route, realized savings, and shadow-mode recommendations so teams can verify what changed.
Illustrative example only. Actual savings depend on your approved model basket, traffic mix, and prompt shape.
Up and Running in Minutes
Change one line. Get access to every major AI model with built-in reliability.
Point Your SDK
Swap your base URL to TheRouter. Works with any OpenAI-compatible client — Cursor, Claude Code, LangChain, your own app.
We Apply Your Policy
TheRouter applies provider health, fallback rules, and your routing objective. If the first route fails, it moves to the next approved path automatically.

Same response format you already use. Plus usage tracking, cost visibility, and team controls — with zero extra code.
