Grok Models API
List models available through the Grok / xAI protocol. The response uses the OpenAI-compatible model-list shape and contains Grok-family models only.
Like every kineticRouter Models API, this endpoint requires a kineticRouter API key. For
Grok / xAI, send it as Authorization: Bearer <your KINETICROUTER_API_KEY>.
