Why Router AI

Not just an API proxy — a control plane that makes your AI stack more reliable, transparent, and flexible.

1 lineto switch providers

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
100%spend transparency

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. Router AI adds health-aware routing, cost visibility, and enterprise security to your OpenClaw deployments.

Cut AI Spend With Guardrails

Router AI helps you compare baseline cost vs selected route, shadow-test cheaper approved models, and prove savings in logs and analytics.

BETA

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.

Baseline: Claude Sonnet 4.6 → Approved alt: GPT-4.1 mini

GA

Prompt Caching

On models whose vendor publishes a cached input rate, cache hits are billed at that rate, not at the full input rate. This matters most for agents and workflows with a long, repeated system prompt.

Where a cached rate is published it is typically 4-10x below uncached input

GA

Measured Savings Evidence

Request logs and Activity show baseline charge, selected route, realized savings, and shadow-mode recommendations so teams can verify what changed.

Logs: baseline vs selected vs saved, per request

ILLUSTRATIVE EXAMPLE: SUPPORT TRIAGE TEAM

Before: every request stays on one premium baseline model

After: baseline stays protected, a cheaper approved model runs in shadow first, then goes live for eligible flows

Illustrative: 20-35% lower model spend

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.

01

Point Your SDK

Swap your base URL to Router AI. Works with any OpenAI-compatible client — Cursor, Claude Code, LangChain, your own app.

02

We Apply Your Policy

Router AI applies provider health, fallback rules, and your routing objective. If the first route fails, it moves to the next approved path automatically.

03

You Get Results

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

Common Questions

Learn how Router AI handles routing, billing visibility, BYOK, and tool compatibility.

Is Router AI just a model gateway?

No. Router AI is the AI infrastructure layer between your apps and model providers. It keeps an OpenAI-compatible integration surface while adding routing, billing visibility, spend controls, and team governance.

Can we keep our existing provider accounts and contracts?

Yes. Router AI supports bring-your-own-key workflows so teams can keep existing provider relationships and pricing while using Router AI for reliability, policy control, and shared visibility.

Does it work with Cursor, Claude Code, and OpenAI-compatible SDKs?

Yes. Teams can start with the OpenAI-compatible quickstart and use the dedicated vibe coding setup flow for Cursor, Claude Code, Windsurf, Cline, and similar tools.

How does Router AI improve reliability?

Router AI applies provider health checks, routing policy, and automatic failover before a request is sent. Teams can verify outcomes with direct provider headers and request traces on the transparent routing page.

What do teams get beyond a single API key?

Router AI adds request-level usage tracking, spend visibility, auditability, and team controls so finance, ops, and engineering can manage shared AI traffic without building that layer themselves.
