Grok
Grok chat models are called through one simple endpoint: send a messages array plus the model slug and get the reply text back. This family exposes 2 models.
Overview
Send a standard messages array (user / assistant / system roles). Billing is deducted from your credit balance per response; the response includes your remaining balance.
Authentication
Create an API key at /api-keys, then send it as a Bearer token. Requests from the browser while logged in also work via the session cookie.
