Qwen Chat

Qwen Chat 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 1 model.

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.

Authorization: Bearer <YOUR_API_KEY>
