The flat-rate OpenRouter alternative: one API key for every major model at a fixed monthly price — with rollover credits and built-in Skills, never per-token billing.
Built for Claude Code, OpenCode & every harness
Why a plan instead of pay-as-you-go? With OpenRouter and raw provider APIs, every token is metered and bills are unpredictable. Router9 gives each harness a fixed-price plan — and unused credits roll over, so cost is a line item, not a variable.
For hobbyists testing and small personal projects.
For developers running everyday agents and coding.

A complete plan: best-value access to every model, rollover credits, and built-in Skills — all under one subscription, one key.
Router9 fronts multiple providers behind one endpoint, routing each request for the best performance-per-dollar — GPT, Claude, Gemini, DeepSeek and hundreds more, all flat-rate.
Install the Router9 Skill or MCP server and your harness gains image generation, speech, vision and web search today — with video generation and more on the way. No extra SDKs.
Every request logged with model, tokens, latency, and status. Export CSV for compliance and analysis.
Point Claude Code, OpenCode, or any OpenAI-compatible agent at Router9 — change the base URL and key, nothing else. A native Anthropic endpoint is available too.
One token plan per account, with as many API keys as you need — one per harness or environment. Usage, quotas, and billing stay unified under a single subscription.
Didn't use your whole allowance? Keep 80% of unused credits into next month — accumulating up to 2× your monthly quota. Bursty months are covered by quiet ones.
