## Alignment Rules

* `llms.txt` is not the complete model catalog.
* Model names, prices, and billing modes come from the [Pricing page](https://crazyrouter.com/pricing).
* Models callable by the current token come from `GET https://api.crazyrouter.com/v1/models`.
* For East Asia, prefer `https://cn.crazyrouter.com`; OpenAI-compatible clients should use `https://cn.crazyrouter.com/v1`.
* When generating API code, prefer route examples already validated on the relevant model pages.
